About this book

THE SUNDAY TIMES BESTSELLING NOVELA BARRACK OBAMA READING PICKSOON TO BE A MAJOR MOTION PICTURE STARRING RYAN GOSLING A lone astronaut. An impossible mission. An ally he never imagined. 'The most enjoyable hard SF I have read in years' GUARDIAN 'Weir's finest work to date. . . This is the one book I read last year that I am certain I can recommend to anyone, no matter who, and know they'll love it.' BRANDON SANDERSON 'If you like a lot of science in your science fiction, Andy Weir is the writer for you. . . This one has everything fans of old school SF (like me) love.' GEORGE R.R. MARTIN 'Brilliantly funny and enjoyable. One of the most plausible science fiction books I've ever read' TIM PEAKE, astronaut ________________________________________ 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 imagine it, 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. ________________________________________ 'One of the most original, compelling, and fun voyages I've ever taken.' ERNEST CLINE, author of Ready Player One and Ready Player Two 'Undisputedly the best book I've read in a very, very long time. Mark my words: Project Hail Mary is destined to become a classic.' BLAKE CROUCH 'Andy Weir's brilliant Project Hail Mary...is one of those stirring sci-fi novels about every government on Earth banding together, through science, to save civilisation from collapse. I loved it.' THE TIMES 'A suspenseful portrait of human ingenuity and resilience [that] builds to an unexpectedly moving ending. A winner.' PUBLISHERS WEEKLY 'Weir returns with gusto . . . his writing flows naturally, and his characters and dialogue crackle with energy. With this novel, he takes his place as a genuine star in the mainstream SF world.' BOOKLIST

In Andy Weir's 'Project Hail Mary,' Ryland Grace awakens from a coma aboard a spaceship, suffering from amnesia, only to discover he is humanity's last hope against an extinction-level threat. As his memories slowly return, he pieces together the desperate mission to save Earth from a sun-eating microbe called 'Astrophage.' Against all odds, Grace forms an unlikely and profound alliance with an alien named Rocky, a creature from a distant star system with a similar existential crisis. Together, they embark on a collaborative scientific quest, overcoming communication barriers and immense challenges, to find a solution that could save both their species.

"I'm going to die. And I'm okay with that. I've had a good life. I'm a good person. I've done good things. I've taught science to kids. I've saved the world. What more could anyone ask for?"
