“If you loved The Martian, you’ll go crazy for Weir’s latest.”—The Washington Post

Ryland Grace is the sole survivor on a desperate, last-chance mission—and if he fails, humanity and the earth itself will perish.

Except that right now, he doesn’t know that. He can’t even remember his own name, let alone the nature of his assignment or how to complete it.

All he knows is that he’s been asleep for a very, very long time. And he’s just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

His crewmates dead, his memories fuzzily returning, Ryland realizes that an impossible task now confronts him. Hurtling through space on this tiny ship, it’s up to him to puzzle out an impossible scientific mystery—and conquer an extinction-level threat to our species.

And with the clock ticking down and the nearest human being light-years away, he’s got to do it all alone.

Or does he?

An irresistible interstellar adventure as only Andy Weir could deliver, Project Hail Mary is a tale of discovery, speculation, and survival to rival The Martian—while taking us to places it never dreamed of going.

Proof that lightning strikes twice ... Weir has done it again!

Reviewed in the United States on May 10, 2021

According to a 2003 article on the NASA website, "NASA-funded scientists have recently learned that cloud-to-ground lightning frequently strikes the ground in two or more places ..." and that the third and fourth strokes of a lightning flash will follow the same path as the second stroke. In other words, lightning DOES strike the same place twice.

But you don't need to search the web for this information. If you want proof that lightning strikes twice, just read Andy Weir's newest book, Project Hail Mary, and you'll see that Weir has created a giant sci-fi bestseller, in the same electric path as The Martian.

Ryland Grace has a puzzle on his hands. He wakes up without a clue as to where he is, but he seems to be alone except for a computer AI that was keeping him alive. Unfortunately it didn't seem to be doing the same for two others in his ... wherever he is ... as he notes the decayed corpses in their creches on the ... well, it's a ship. A space ship. And bit by bit Grace puts the pieces of the puzzle together.

An alien microbe has been discovered. Ryland Grace is brought on to the science team to learn more about the life form because Grace, currently a middle school science teacher, wrote papers about the notation that there does not need to be water to create life. Only in a biozone such as Earth's would water be needed, but other building blocks could be used in other systems.

The science community as a whole mocked Grace, which is why he left and went on to teach kids, but now, he may be the best suited to understand this new life form. And as he remembers more and more, he also remembers that this life form is feeding on the energy output of the sun, which is decreasing the energy that gets to Earth, which spells disaster - as in the end of all life as currently known - on Earth if something isn't done.

Scientists discover that Sol isn't the only star that is losing its energy output - likely due to the alien consumption, but that there is one star, in the center of all the known stars losing their energy, that remains constant with its output. In which case, the answer to the survival for Earth is likely found there, at Tau Ceti.

The world's best scientific minds come together (by force and coercion) to create a ship that can get to Tau Ceti in twelve years (using the alien microbe as fuel) with shuttle pods to bring back answers to how to save the planet, but for the crew, it's a one-way trip.

Knowing why he's there is only the first puzzle for Grace. Now he has to figure out how to save Earth. There's a very small window of time for him to discover the way to save the human race and get the answers sent back. Take too long and the shuttles will return to a dead planet.

This book is amazing.

Author Andy Weir brings us back to the magic that made The Martian so successful - an abandoned scientist trying to survive. But Ryland Grace's story is more complicated because he's not just trying to survive, but also help humanity survive.

There's lots and lots of science - which is part of Weir's writing signature - and there's also a really wonderful story.

It's hard for me to tell you just what I liked about this book because anything I write will be a spoiler and a huge part of the joy in this book is making the discoveries with Ryland Grace.

Grace is our main character, but through the liberal use of flashbacks, we have a full cast of characters - at least one quite important to the story. Everyone is unique and individual which makes it easy to read, but just as with The Martian, where Mark Watney's personality carries the story, Ryland Grace here is the smart-mouth, sometimes funny, obsessed scientist infusing his personal tastes into his discoveries. He's also quite smart - which is good since he will need his intellect to save all of humanity.

This is a page-turner. I did not want to put this book down. Neither did my 21 year old son who picked up my copy after I was well into it and finished it before I did. And days later he's still talking about how much he liked it and quoting sections of it to me at the dinner table.

I hope Ballantine Books will do a very large print run because this is going to be huge seller and you definitely don't want to miss out on the biggest thing to come out in 2021.

Looking for a good book? Project Hail Mary by Andy Weir is proof that lightning strikes twice as this has all the excitement and energy of Weir's debut novel, with a more complicated storyline that will hold the reader all the way to the end.

Astonishing, Fun, Entertaining, Fantastic

I consider The Martian my favorite fictional novel of the last 15-20 years. The movie was incredible in that they actually followed the book closer than 99% of other films based on books. It remains my favorite movie of the last 15 years or so as well. I don't know anyone (personally) that loves either of them as much as I do.

With that said, I was REALLY looking forward to Artemis. It was good...but, it was certainly not in the same caliber as The Martian was (at least not for me). I enjoyed it a lot, however and appreciated how author Andy Weir chose to go in a completely different direction and not just rehash another similar story, which I am certain would have been great as well.

As a result, I was cautious regarding Project Hail Mary. It sounded a little too close to The Martian, but yet, also different in that the circumstances simply could not be more opposite and the stakes so much higher. I'm trying to figure out the best way to summarize without giving too much away from this utterly compelling novel. As I read several reviews, I noticed a recurring theme: SCIENCE. Lots and LOTS of science. Holy cow, they were right. Many years ago I read Apollo 13 and Jim Lovell and his co-writer, try as they might, simply could not dumb down Orbital Mechanics anywhere near enough for me to have even a minor clue as to what they were attempting to say...I just skipped 90% of it and hoped that the sentences written afterwards, would help to make sense of what I had just skimmed over. I'm a lot of things, but a math wizard is definitely not one of them. Michael Crichton (Jurassic Park) had an amazing talent for dumbing-down the science of what he was trying to explain in ways that genuinely made sense (most of the time). Not everyone has this talent, and I would say Andy Weir falls squarely in between. He's certainly better than Jim Lovell, but not quite as good as Crichton. But then again, outside of a science textbook, I haven't really read anything with quite as MUCH science as Project Hail Mary. So maybe he's just as good, but he just puts more science into his books than Crichton, maybe that's it...? Either way, be prepared for a lot of astonishingly interesting science within the pages of this novel...and I DO mean a LOT. I don't say this to make you wary or steer you away...on the contrary, Andy Weir has a special talent for making hard science truly entertaining.

The book opens with an absolutely amazing and frightening premise: an astronaut awakes from an induced coma to find the only other two people on board have died at some point along their journey...but it gets worse. He has no idea who he is, or why he's on the ship, and oh yeah, they look to be a long way from home. A really, REALLY long way from home. In fact, the sun he sees isn't actually OUR sun at all. He's managed to leave our solar system entirely. And he has no idea why.

((Minor Spoilers)) The book goes through some clever flash-backs, which set the stage for why the mission happens, and slowly, carefully explains how they managed to get so far away from earth in such a short amount of time. Basically, earth's sun seems to be dying. At the rate of decay, we have maybe 19 years left before the gradual cooling has catastrophic consequences resulting in the death of billions (best guess). Why the sun is dimming is quite the conundrum in the first place. Turns out it really isn't dying, it's being killed by an outside source...which turns out to be easily the greatest find in history. It's alien life, and they are using the sun for food, essentially. It's alien life, but not intelligent life. But still, wow! ALIENS, right???

After this monumental discovery, and some tremendous research done by the most improbable scientist, the investigation into what is happening and why and what to do about it expands exponentially to other nations in order to pool all the resources possible to hopefully save the sun, and by extension, the human race as well. They learn. A LOT. A plan is put together, and with the help of the newly discovered microscopic alien life, which can also double as a power source (along with a few other nifty surprises), they begin to create one last, Hail Mary that could very well be the last chance we might have to save earth. It's audacious. It's dangerous, and it is absolutely critical that it succeed.

As our astronaut's memory slowly unravels, so does his identity: Ryland Grace. He's a teacher on earth. Just a science teacher. Not even a college professor. He's amazingly smart, though. But he's no astronaut...and certainly not one who would volunteer to go on a one-way mission to another solar system to "try" and save humanity. Yet here he is. Alone. light years from earth, trying to solve the biggest riddle in all of human history. Ryland accepts his situation, such as it is, with relative indifference (for the most part). It doesn't matter HOW he got here. He's here now and he may as well use that time to be as productive as possible, right? Along the way, he unravels even more information regarding the microscopic alien life which is slowly dimming our sun during some additional flashbacks. The aliens, dubbed, "Astrophage" are quite the galactic plague as it turns out. Stars all over the galaxy are also losing their light, all due to the little buggers. All that is, except one particular star named, Tau Ceti. Now why would that one star be unaffected by Astrophage, when every single star around it has been affected to some degree. The plan is to go there and figure it out and send the information back, hopefully in time to save the sun before the damage to earth is beyond repair.

There is an incredible amount of stuff going on. The story switches from Tau Ceti to flashbacks of how the whole mission was planned and implemented (which is VERY entertaining, especially Director Stratt, who may actually be my favorite character in the entire novel). Weir is becoming quite adept at building tension, and abruptly switching the story from Tau Ceti back to earth and building more of the backstory then switching back to Tau Ceti. Keeping it all in check and most importantly, interesting all while mixing in a healthy dose of science, which I am to understand is pretty much all genuine, is quite the juggling act. I have long known science can be astronomically entertaining (see what I did there?) when done right...but unfortunately very few people in a position to teach science actually know the best way to create that interest in others. I can say without reservation, Andy Weir definitely knows how to do it...at least in written form.

There is so much I want to say more regarding this truly phenomenal story, but I simply cannot without ruining a lot of the fun and surprises revealed along the way...and it is killing me to keep it locked in. Though I labeled a spoiler warning earlier, I don't think it gave away any more than what the author himself has revealed in interviews he has done regarding the book, and what you can glean from reading the summary here and just a couple other reviews. Tying all of that science together is truly astonishing to me. The creativity to put it into a novel that is remarkably exciting to read is nothing more than incredible talent. Kudo's to Andy Weir for not just hitting a home run, Project Hail Mary is a Grand Slam all the way. I truly did not want this story to end. By the way, I enjoyed the ending quite a bit. I don't know if everyone will. But it was fine for me. I think the ending screams "sequel" at some point too. A lot was left open-ended (IMO) and I wouldn't mind reading a follow-up to this. It doesn't HAVE to happen, but there are a lot of ways where the story could go if Andy chose to do it. Just sayin'.

Just run out and buy this book.

What a phenomenal book. I haven’t read Weir’s other novel, The Martian, but I may have to go there after reading this. This story was intriguing, inspiring, and uplifting. I couldn’t stop reading. I enjoyed the scientific aspects with experiments and math and such, but it wasn’t overwhelming. You’ll finish this book feeling smarter! The characters were presented well, easy to relate to, and made me smile every step of the way. If you’re looking for a smart, intriguing novel with a dash of space adventure, you need to read Project Hail Mary!

A wonderful Sci-Fi Novel with freshness of thinking

Reviewed in the United States on June 24, 2024

Project Hail Mary by Andy Weir has been in our digital library for quite sometime now and so happy to finally have read/listened to it. It’s a wonderful Science fiction novel with some interesting, fresh and unique perspectives, both with the plot and with the ending. Even though it’s actually a fiction, it’s been written with nice interesting details about the space voyage and the experiences of Ryland Grace in first person, the interstellar traveling scientist, almost to a point that it felt very realistic. I appreciate the efforts Andy Weir has put into writing this book with such vivid elaboration.

A few years ago, I listened to the audiobook The Martian and really loved it. It was actually a very interesting and hearty reading. This book felt quite intense, especially compared to The Martian and yet it’s so well written that I am also planning on reading Artemis eventually. Also, this book is certainly longer than The Martian. And, while I read kindle books and listen audio books, this had been my first time reading a kindle book while simultaneously listening to the audiobook and the experience is certainly immersive, especially for Rocky’s musical notes and sounds. :) Ray Porter did a great job of narration. Overall, it’s a wonderful book that got me interested in Tau Ceti and then Erid. Definitely one of the good books.

P.S. Not sure why there weren’t multivitamins for astronauts in this book while there were for The Martian. I am assuming there must be even if it’s not mentioned which doesn’t explain scurvy or beri beri. Also, I am unable to stop thinking of the ending especially from the part where Grace meets Rocky again and the story there after. The ending felt a little abrupt honestly and a bit short for the otherwise elaborately well written book that actually got most hows explained (except for the last part of course).

Not your typical SciFi story

Reviewed in the United States on June 17, 2024

The science in this book is the prevailing thread. Pseudo science or not, frankly, it stretched my armchair scientist database. If you don’t have the patience for loooong passages of science, this is not the book for you.

However, if you do have the patience, then you’ll enjoy this fresh take on a Sci Fi story that, as so many SciFi stories do, ‘saves the world’.

Here’s the upshot: The sun is dimming thanks to a microscopic life form that breeds by eating light. With a dimmer sun, the ecosystem of Earth will collapse and spell the end of humanity. Nations come together to build a ship that can go out with 3 science astronauts and hopefully fix the problem. The only scientist left alive on board meets another ship from another planet facing the same problem and with only one left alive there, too. The Earthling is a scientist. The Eridian, a crustacean spider-formed being, is an engineer. From atmosphere and food requirements to language and cultural norms, they are diametrically opposed on most fronts. Yet, together, they solve problem after problem to ultimately save both their worlds.

The ending? Without giving spoilers, it wouldn’t have been my first choice and, yet, it was oddly fitting. Why not give 5 stars? There was just a little too much science and the social outcome on Earth was left hanging.

A Hard-Science-Fiction Book, not for the Impatient nor Weak of Curiosity

Reviewed in the United States on December 25, 2022

• A hard-science-fiction book, not for the impatient nor weak of curiosity. While the author goes to extraordinary lengths to explain the physics & science behind just about EVERY action taken by the protagonist (Dr. Ryland Grace), the explanations can get tedious, overbearing, and at times, pedantic. Indeed, the book does not really get going/interesting until about 33% through it. That’s an interminably long time for readers who want a quick space romp with some occasional science thrown in. This is not so much a character-driven story as it is a science-driven one. If you didn’t read his book-made-into-a-movie, “The Martian,” and you’re expecting a fast-paced plot like that in the movie, you’re going to be disappointed. Buckle in and ready yourself for myriad avenues of political and scientific machinations behind overcoming (hopefully) a human-extinction-level event. • As an engineer and physics lover, I liked parts of the beginning of the book where it may have bored many other readers. However, after a while, I, too, grew tired of the endless explanations. I kept searching for the plotline, hoping Andy Weir would pick it up again and run with it after some initial world-building is complete. Alas, that did not happen. But if you can stick it out for the first third of the book, I promise you, it will suddenly improve around the 34%-35% mark. • At 482 pages, it’s a thicker-than-normal book, and that’s primarily because of the intense (and extended) world-building that goes on throughout the book. Science nerds might love it, or they might hate it because they already know all the science behind the story. Those less scientifically educated might be enthralled to learn about the real principles behind rocketry and space travel, or they might be completely bored by all the explanations and slow plot (at least for the first third of the book). I think if this book ever gets turned into a movie (can’t see that happening), a great deal of the book would HAVE to be cut out to fit it into a two-hour window and not bore the heck out of the audience. • In the latter 20% of the story, the plot once again slows down. In particular, the explanations of the various experiments Dr. Grace is performing onboard with different microorganisms once again strain the brain and slow the plot. Some of it was downright confusing (with too similar wording used for the different “breeder farms” he has set up) so I had to go back and re-read what Weir had written to fully understand it. However, the ending was a nice surprise, satisfying and sweet. As a fellow sci-fi writer & lover, I was wondering about the possible direction(s) the author would take w.r.t. Dr. Grace’s return to Earth. I was pleasantly surprised by his choices. • SPOILERS AHEAD! I very much enjoyed the real-life implications of relativistic interstellar travel, the red-shift phenomenon, and what it would ACTUALLY take to travel thirteen light years to a distant star, this one being Tau Ceti. I learned a lot about that star, and Weir sparked my curiosity about that star system, enough to force a new browser tab in my Wikipedia collection! Most of all, I loved the character of “Rocky”, the alien that Grace meets. The humor and interpersonal skills involved in establishing First Contact were done exceptionally well (particularly, Grace’s Excel spreadsheet solution for a language translator—very clever!). I openly laughed many times at their frustrations and miscues from colliding cultures (e.g., the “fist bump”), social idioms, and language barriers. Weir’s handling of their very diverse living conditions was especially intriguing in trying to see how (if at all!) they could co-exist in the same space. The author leans a little too heavily on “xenonite”, a fictitious material that seems to solve (nearly) all problems. But hey, this is a sci-fi novel, so that’s allowed! I also enjoyed his portrayal of mission control commandant Stratt. I cheered on her no-holds-barred approach to telling the rest of the namby-pamby infighting humans to STFU and get on board. Her persona is probably EXACTLY what we would need if humans were faced with an extinction-causing event of this magnitude. • In summary, while you don’t have to understand all the physics/science behind what Dr. Grace and Stratt & Company do, I think you’ll lose one-third to one-half of the “nerd thrill” buried within the plot. Weir does a good job explaining it in layman’s terms but at the expense of the plot’s pace. Be patient; he finally gets there, and it’s a fun ride.

Lost in Space

I loved the movie The Martian and thought I’d try the new Andy Weir book. It’s my first encounter with this author, and at first I was a bit thrown off by the use of first person perspective, but in the end I decided it fit the story perfectly.

It’s about a man waking up on a spaceship having no memories of himself or his surroundings. Classic setting, and one that worked well for the story. All in all I loved the book, but there were a few inconsistencies or errors that prevented me from giving it five stars.

I read the book using the Kindle app, and the first impression is that the text should’ve been justified. But I guess the author had someone else do the formatting, so I won’t blame him. However, as an American he should really know how to write the caliber of a bullet. It’s usually measured in milimeters or inches. On page 59 he writes «Which is like shooting a 50-caliber round at a sheet of paper …»

I’m pretty confident he meant «… shooting a .50-caliber round …» because that bullet is half an inch in diameter, and in Norway we call it 12,7 mm.

The next thing that makes no sense is a few pages later. «You guys know about climate change, right? How our CO2 emissions have caused a lot of problems in the environment?»

Our CO2 emissions? Problems in the environment? More CO2 means a greener planet. Plants use CO2 for photosynthesis, and more CO2 makes them grow faster and use up less water. Why do you think farmers pump more CO2 into their greenhouses? It’s good for the planet, not bad, especially now we’re in a time with historically low CO2 content in the atmosphere, meaning many species of plants are almost at a starvation level.

Besides, human emissions are tiny compared to those of nature herself. Fifty active volcanos, anyone? And most of it comes from the ocean anyway, and that’s where any excess CO2 would end up too.

And then he presents one and a half degree temperature rise as a problem. Excuse me? One and a half? It was much warmer during the Holocene Optimum. Maybe he should read some history? Talk to some geologists? The Earth has been much warmer before, and we know this from ice core samples and tree ring data. Civilizations thrived. The Roman Empire, Chinese Han Dynasty, the Vikings settled Greenland and Newfoundland. No, cold is the enemy, not warmth.

Looking past these rookie mistakes I found the book entertaining and fun. Great sci-fi. Great dialog. Loved Rocky and how his entire species was described in detail. I just love it when an author put this amount of detail into his stories. Also amazing detail on the spaceship and its unorthodox fuel.
