“An epic story of redemption, discovery and cool speculative sci-fi.”—USA Today
“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.

Project Hail Mary by Andy Weir
Andy Weir, the bestselling author of The Martian, returns to form with Project Hail Mary, a gripping blend of hard science fiction, survival adventure, and unexpected heart. The novel once again showcases Weir’s signature strengths: a sharp sense of humor, scientifically grounded problem-solving, and a protagonist you can root for.Plot Overview (No Spoilers)The story follows Ryland Grace, a man who wakes up alone on a spaceship, suffering from amnesia. He doesn’t know his mission, his name, or why he’s hurtling through space — only that Earth’s survival somehow depends on him. As his memory returns piece by piece, so does the scale and urgency of his task.What follows is a brilliant mix of science-driven problem solving and mystery unraveling, with a healthy dose of tension and surprising emotional depth.Unique Twists: The novel introduces an alien life form and first-contact scenario in a fresh, original way that avoids cliché and instead emphasizes cooperation and communication.Final ThoughtsProject Hail Mary is a triumphant return to the kind of smart, optimistic sci-fi that made The Martian a global hit. It’s a celebration of curiosity, resilience, and the human spirit — and it might just make you laugh, cry, and Google astrophysics terms all at once.If you enjoy character-driven science fiction where science is both the obstacle and the solution, Project Hail Mary is a must-read.

Project Hail Mary: Smart, Suspenseful, and Surprisingly E
🌟🌟🌟🌟🌟I picked up Project Hail Mary after watching the trailer for the upcoming movie, and wow—I’m so glad I did. The story pulled me in from page one and kept me hooked with its perfect blend of science, suspense, and heart. Andy Weir somehow makes astrophysics feel thrilling and accessible, and the emotional arc is just as powerful as the technical ingenuity. Reading it after seeing a glimpse of the film made the experience even more immersive—especially imagining Ryan Gosling as Dr. Grace. Absolutely worth the hype. A smart, funny, and surprisingly moving space odyssey.

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

A very simple story and nicely written with an optimistic view on alien encounters along the way. It was also my first encounter with Andy Weir’s literature.From a scientific point of view the science weaved into the story seems reasonable – though I did not exhaustively validate it – but I never encountered a passage, where I had to say, this is simply impossible.If you look for entertainment with optimistic sci-fi, I believe that Andy Weir got you covered with this book.

Project Hail Mary is one of the most gripping, emotionally satisfying, and cleverly written sci-fi novels I’ve ever read. From the very first page, I was hooked by the mystery and momentum—and it never let go.The story blends science, survival, and humor with perfection. The pacing is spot-on: never slow, never rushed. Just like The Martian, Andy Weir’s signature wit shines through, but here he adds a surprising amount of heart and emotional depth—especially in the bond between the characters.The climax is absolutely epic, and the conclusion left me stunned in the best way. It’s not just a great sci-fi story—it’s a celebration of friendship, sacrifice, and problem-solving at the edge of the universe.If you want a book that makes you laugh, think, and maybe even tear up a little—this is it. A modern sci-fi classic.

Si han leido The Martian por Andy Weir, dejame contarles que Hail Mary es todavia mejor! La narrativa es semejante en donde el protagonista resuelve problemas conforme van surgiendo. Todavia mejor es que nuestro heroe Ryland Grace es el unico sobreviviente de la mision y encuentra un Alien -al que llama Rocky- en una mision semejante y juntos trabajan para salvar sus respectivos mundos. Una lectura altamente recomendable!
