NEW YORK TIMES BESTSELLER • From the author of The Martian, a lone astronaut must save the earth from disaster in this “propulsive” (Entertainment Weekly), cinematic thriller full of suspense, humor, and fascinating science—in development as a major motion picture starring Ryan Gosling.

“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.

This is the first book that I have read by Weir and I have to say that it is so brilliantly written that I could barely put it down. In fact I put it down only when I absolutely had to! The way he developed the protagonists of the book had me so incredibly emotionally invested that I cried twice while reading! If you’re looking for a Sci-Fi book with humor and heart then this is absolutely the book for you!

Fantastic Story and SciFi Details

This one book I thoroughly enjoyed. It probably helps that I’m an engineer. Great storytelling and amazing technical details. It will make a great movie I’m sure.
