NEW YORK TIMES BESTSELLER • A lone astronaut must save the earth from disaster in this “propulsive” (Entertainment Weekly) new science-based thriller from the bestselling author of The Martian.

“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.


  • Fun and heartfelt. A winner.

    By Gus McCrae
    This book won me over right away. Weir again tells an explosive story with gobs of heart. He weaves in plenty of science, of course, but the real stars of this book are the main characters. Just, wow. Incredibly warm and almost beautiful. Bravo.
  • Wow

    By Lomonoji
    Read it in a week, couldn’t put it down. Reminds me of Asimov.
  • A fun read

    By DadChompsSam
    Mark Watney saves the world… seriously, Andy has created a whole new genre… science-science fiction. It’s not a story that takes place in space, rather it’s a story where science and engineering are heroic themes. Your 3rd book took some time to get going, but by the 3rd act you were on fire. A great book. Thank you for writing it.
  • Read again,again,again....

    I don’t hand out 5 stars Willy-nilly. Thank you Mr Weir for an exceptional story!
  • Gotta love a good happy-sad-ish ending

    By Abolina
    Picked up this book cause I loved “The Martian” & loved this book as well. “Rocky” is a cute character. Great story, chock full (maybe too full? Na.) of scientific detail. Another great book ending by Weir, that’s what it’s all about, isn’t it? When you can tear-up a bit on a SF novel, that’s a great novel.
  • Derivative but still fun for us geeks

    By Two Way Miss
    Basically a redux of the Martian in framework with a number of tried and true feel-good story telling moves. Easy reading if you like to get in the tall grass with science. Won’t change your life, though
  • Sci-fi of the finest tradition

    By ABK097
    A joy to read, and in line with The Martian in tone and scope. Like The Expanse, this is Sci-fi on our timescale, making it relatable and generally understandable to intelligent minds or science geeks. Yet like the more fantastical and groundbreaking sci-fi of television and movies (Trek, Dune, Battlestar Galactica, etc.) also serves to comment on the current times. I especially appreciate the humor; just like when I read The Martian, I was laughing out loud, and my face was leaking. Good good good! 🎵🎶!
  • Fantastic, fun, ride

    By ericandi
    Once again Weir hit a home run. Science, adventure, suspense, and thrills in one package.
  • Can’t wait for the movie!

    By David Dorough
    I got sucked into this plot right away. Lots of twists and surprises to keep me turning those pages. Great second novel. Looking forward to number 3.
  • All Hail Andy Weir

    By Mysteryjunkie
    Better than the Martian if you can believe that! First half of book was a fast paced, science oriented, amazing read. (I’m not really a science person but really interesting!) Next couple chapters is the story of an unlikely friendship which carries through the rest of the book. The end ties it up in a way I think everyone will love. I had to stop reading a few times. I was buzzing through and I didn’t want it to end. I usually read thrillers. This is a thriller in space!
