Project Hail Mary

Project Hail Mary by Andy Weir

The #1 New York Times bestselling science fiction phenomenon from the author of The Martian—now a major motion picture starring Ryan Gosling. Project Hail Mary is an unforgettable space adventure packed with suspense, humor, scientific discovery, and one of sci-fi’s most memorable friendships.

Ryland Grace wakes aboard a spacecraft millions of miles from Earth with no idea who he is, why he’s there, or how long he’s been asleep. His crewmates are dead. His memories are missing. And as far as he knows, he is completely alone.

Then the truth begins to return.

Ryland is the sole survivor of Project Hail Mary, a desperate mission to solve a scientific mystery threatening the survival of humanity. If he cannot find an answer, Earth—and everyone on it—faces an extinction-level catastrophe.

Armed with little more than his intelligence, scientific knowledge, and determination to survive, Ryland must piece together his forgotten mission while racing against time to understand a threat unlike anything humanity has encountered before.

And just when it seems he must save the world entirely on his own, Ryland makes a discovery that changes everything.

Smart, funny, suspenseful, and surprisingly emotional, Project Hail Mary combines hard science fiction with an irresistible survival story and a remarkable tale of friendship, sacrifice, discovery, and hope. Andy Weir transforms an impossible interstellar mission into a page-turning adventure that appeals to longtime science fiction readers and newcomers to the genre alike.

A Hugo Award finalist and New York Times Readers’ Pick for the 100 Best Books of the 21st Century, Project Hail Mary has become a modern science fiction favorite and inspired the major motion picture starring Ryan Gosling, directed by Phil Lord and Christopher Miller with a screenplay by Drew Goddard.
