“"Hail Mary" by @andyweirauthor is one of the best fiction books I've read in a LOOOONG time! • It's a "hard science" novel so all the physics are real, but the story is fiction. • You get captivated by the story, but also learn some clever engineering in the process! • 10/10 | @andyweirauthor Can’t think of a better place to read it brilliant book @andyweirauthor | Best sci fi book i've read in a long long time. Has lots of real science/engineering in it. Incredible read. | I just finished Project Hail Mary by @andyweirauthor and it’s easily one of the best scifi books I’ve ever read. and I read a LOT of them. my highest rec from 2021. | If you want to read something that celebrates science at its core, read Project Hail Mary from @andyweirauthor. An excellent and brave science fiction book! | Like most people, I was first introduced to Weir’s writing through The Martian. His latest novel is a wild tale about a high school science teacher who wakes up in a different star system with no memory of how he got there. The rest of the story is all about how he uses science and engineering to save the day. It’s a fun read, and I finished the whole thing in one weekend. | Perhaps the best audio book I have heard! #projecthailmary by Andy Weir is great but the performance of Ray Porter of all of the characters is award winning. I cannot stop listening. Sooo good! | Project Hail Mary: 5/5 stars. I have no idea why this book was so much fun, but it was really, really good. The science was clever, the story was great. | Read 30 books this year and the best ones were Gideon the Ninth by @tazmuir and Project Hail Mary by @andyweirauthor! Looking forward to 2023! | The hype around Project Hail Mary is real. One of the best books I've ever read and couldn't put it down. Highly recommend checking it out especially if you love scifi | The plot of Andy Weir's PROJECT HAIL MARY consists mostly of science problems and their solutions. Joyously.

Reading Profile
Should I read this?
Project Hail Mary opens with an amnesiac astronaut waking on a spaceship, and the fun is watching him piece together his identity and apocalyptic mission. The book is driven by scientific puzzles—every crisis met with experimentation and calculation—but it’s buoyed by a warmth that arrives with an unexpected alien ally. What works best is a clever, can’t-put-it-down plot laced with optimism. The limitation: for some readers, the frequent, detailed science asides will feel like lectures that stall the momentum.
Read this if...
- •A research scientist frustrated by sci-fi movies that ignore real physics—this novel makes accurate problem-solving the center of its crises, not an afterthought.
- •A burnt-out product manager who needs a story that replaces cynicism with can-do optimism and delivers frequent, satisfying payoffs to rebuild a sense of momentum.
- •A high school physics teacher designing a space-science module who wants a story that shows students how hypothesis, experiment, and recalibration can literally save a world, not just fill a worksheet.
Skip this if...
- •You’ll likely put it down when the protagonist pauses to detail orbital mechanics or the chemical properties of an alien atmosphere—these multi-page science asides feel like lectures if you prefer action to move without detours.
- •The protagonist’s relentless optimism and the alien friendship’s earnest sentimentality will grate if you need morally gray characters or emotional bleakness in your sci-fi.
- •Skip it if you prize literary prose or ambiguous endings—the workmanlike writing prioritizes plot clarity, and the resolution ties up all threads with a heartfelt but tidy bow.
THE #1 NEW YORK TIMES BESTSELLER FROM THE AUTHOR OF THE MARTIAN • Soon to be a major motion picture starring Ryan Gosling, directed by Phil Lord and Christopher Miller, with a screenplay by Drew Goddard A lone astronaut must save the earth from disaster in this “propulsive” (Entertainment Weekly), cinematic thriller full of suspense, humor, and fascinating science.

Not sure if this is the right fit?
Consider Sapiens by Yuval Noah Harari. Recommended by 101 sources.
“A sweeping narrative history of Homo sapiens from the Cognitive Revolution to the present. Harari argues that what makes humans dominate the planet is not physical strength but collective myths: shared fictions like money, religion, and nations that allow millions of strangers to cooperate. The book moves fast through 70,000 years, making big, debatable claims about agriculture, empire, capitalism, and happiness. It is less a history textbook than a provocative essay in chronological form, and best read as an argument rather than a reference.”
