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.

Ryland Grace, a former science teacher, awakens on a spaceship with amnesia, millions of miles from Earth, to find his crewmates dead. As his memories gradually return, he pieces together his desperate mission: to save humanity from an extinction-level threat called Astrophage, a microscopic organism consuming the sun's energy. Facing impossible scientific challenges and overwhelming loneliness, Grace discovers he is not alone in the universe when he encounters an alien named Rocky from a different star system, also on a mission to save his own species. Together, these two unlikely allies must bridge their communication barriers and combine their scientific knowledge to avert dual planetary disasters.

"See? I told you. There's nothing you can't do." (Rocky)
