The #1 New York Times Bestseller from the author of The Martian. Now a major motion picture starring Ryan Gosling.
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.
Why this is a sci-fi masterpiece:
-
Hard Science: Just like The Martian, this book respects the laws of physics. It treats science not as magic, but as a toolkit for survival.
-
The Ultimate Puzzle: Waking up with amnesia in another solar system is the ultimate "locked room" mystery—except the room is a spaceship and the key is astrophysics.
-
Optimistic Speculation: A thrilling look at first contact and what it really means to communicate with a completely alien intelligence.
🔭 From the Desk of Paul Bracken:
"If you liked The Martian, you will love this. Andy Weir does something few sci-fi authors do: he makes the math part of the thrill. As an astrophotographer, I loved the details about Tau Ceti and the relativistic travel. It captures that feeling of looking through a telescope and realizing just how vast and strange the universe really is."
