Project Hail Mary: A Novel

Andy Weir’s latest novel continues a theme of blending scientific knowledge to solve problems and the perils of outer space exploration. In this tale, a middle-school science teacher, Ryland Grace, is faced with a seemingly insurmountable task, saving earth from a cooling sun. Long before he became a science teacher, he wrote a paper about the possibility of the existence of life forms that don’t need water to survive. At the time, his analysis was widely rejected and ridiculed. Now, because it appears that life forms are responsible for draining the sun, he has become a visionary and is tasked with working with a group of international scientists to find a solution for a what could be a global catastrophe. Through scientific experiments, Grace and his team determine that the microscopic organisms he calls “astrophages” are a threat to humankind and must be stopped. But how? After a series of tragedies and misadventures, Grace wakes up years later in a space-craft. His memory slowly returns as he has been placed in an induced coma with robots and computers tending his biological functions. The most incredible and fantastic event occurs when he meets another being with the same objective he has. The story goes back and forth in time showing how Grace ended up in the space-craft and his current dilemma of finding a way of counteracting the astrophages. The novel incorporates a wealth of scientific knowledge along with generously placed doses of humor. This is a book that will appeal to a wide readership, from teens interested in science, to adults intrigued by sci-fi and adventure. It’s a satisfying and enjoyable read and creates a feeling of wonder.

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.

I’ll start with a review of the physical book itself: It’s a book, there isn’t much to say. The binding was easy to break in without taking damage or breaking off. It’s got a nice finish to it, and is very readable. It also contains some diagrams that help visualize some key components of the story. That brings us to a review of the story itself. There’s no denying that the story is captivating, and I really loved the scientific accuracy and detail. Andy Weir anticipates nearly every reader / audience question, and answers it thoroughly and accurately. After watching and loving the movie, I couldn’t get enough of the book, which answers nearly all my questions. I would call the writing a bit plain: on the one hand, this lends itself to an easy read, and to the scientific portions being understandable by the layperson; on the other hand, it does lack a kind of poetic excellence that you would want for the emotional parts of the story. Dialogue can fall flat at times, or the emotional affectation of a character doesn’t feel properly justified. I wish that the pacing of the writing handled narrative buildup and climaxes better, rather than being somewhat constant, and thus unexciting. All that to say, it’s an easy read with a very killer story. If you watched the movie and want more of the story, the book is excellent. I particularly applaud the in-depth astronomy, relativity, and other science aspects that the movie glosses over. You also get to know Grace and Rocky better, which is always welcome.

Andy Weir has done it again with this absolutely gripping space adventure that kept me turning pages late into the night. The scientific problem-solving is fascinating and well-researched, making every challenge feel both authentic and engaging. What really sets this book apart is the perfect balance between hard science and genuine emotion - I found myself laughing out loud at the witty dialogue while also being deeply moved by the relationships that develop. The protagonist's journey is compelling from start to finish, and the way the story unfolds with its clever reveals and plot twists is masterfully done. If you enjoyed The Martian, you'll love this even more - it's everything that made that book great, elevated to an entirely new level.

Such a surprising and engaging book! The entire concept is intriguing, and there are many unexpected plot twists that make this a real page turner that I could not put down. The way the two main characters interact and build upon their relationship is memorable. They use their combined scientific knowledge to overcome seemingly insurmountable problems, while working towards the goal of saving their world. It seems to be a trend recently have open ended, unfinished, and unsatisfying ends to a book. This is not that kind of story. It is brilliant from beginning to end! By far one of the best book I've read in years.

I could not put this book down. I did not think that Andy Weir could top The Martian, but he has. The premise is brilliant. Before I knew it, I was totally invested in the main character. And when Rocky came on scene, the story became even more compelling. The science is, at times, beyond me but I trust Andy Weir will not lead me astray. Scan those parts if you like. You always understand the outcome. I did not see the ending coming. It was heartfelt and wonderful and totally worth the journey.

This book was SO good! If you read The Martian, you've got to check out Project Hail Mary! And read the book before you see the movie. There is so much detail in this book, so much science, I honestly felt smarter while reading it. At the same time, it wasn't too much. It was just understanding the main characters thought process. He walked you through ever problem he encountered and how he found a solution. It was a rollercoaster of emotions! Incredibly well written! I couldn't put it down.

Many people can relate to the experience of waking up and having a Jumanji-esque "what year is it" existential crisis - which of course is usually in jest, or quickly passes. For Ryland Grace, waking up is an altogether cataclysmic experience - he can't remember his own name, or what he's supposed to be doing, or why there's two corpses and a robot in the room with him. With time, his memory's return in the hazy way a dandelion's seeds float on the wind - and he's slowly reacquainted with the impossible nature of his task. Alone and hurtling through deep space on a veritable chimera of a ship fueled by every government agency on the planet, he's humanity's last hope against an extinction-level event taking place back at home. And with the unexpected help of an ally, the odds may just be in his favor. I walked into this book fairly blind - it was my book club's choice ahead of the movie adaptation coming out this year, and I missed out on "The Martian" when it was popular, so I was pleasantly surprised with how much fun (and anxiety) I had while reading about Ryland Grace (main character name if I ever saw one) and his schoolteacher smarts fighting it out at the brink of the universe. The book did a good job in slow-baking a lot of nebulous concepts into something the average reader could parse out and enjoy, which I think can be difficult for science fiction books - and while I doubt much of the science will stand up to proper scrutiny, this isn't one of those books that's diving into realism. You're here to have fun, and maybe review some of what you've forgotten from high school or entry-level college courses, and that's okay. I think the book did a great job in capturing the desperation of what the internet cryptids would call an "XK Class End-Of-The-World Scenario" and took a good stab in imagining what that might look like from a world government/cooperation standpoint, if with heavy liberties towards how maturely some world leaders would act. I think the humanistic and scientific facets of the mission, which was revealed in piecemeal as Grace's memory catches up, worked really well from a pacing and storytelling perspective, and while there were loose ends I really wanted follow-up on that were never tied up properly, I don't think this necessarily ruined my enjoyment of the story overall. I'll be looking forward to seeing how this one plays out on the big screen since there's a lot of internalization and explanation from a reader standpoint, but overall I'd be up to reading more Andy Weir stories in the future.
