Just when you think the book is going to be The Martian 2.0 —a lone human fighting the void with duct tape and chemistry—Weir throws a curveball so brilliant it changes the entire genre of the book. Grace discovers he isn’t alone

If you liked The Martian , you will love this. If you were intimidated by the hard sci-fi of The Three-Body Problem , you will prefer this. If you just want a fun, smart, gripping adventure about two very different beings trying to get home? This is for you. Just when you think the book is going to be The Martian 2

It sounds like the setup for a grim, two-hour horror movie. But Andy Weir—the genius behind The Martian —doesn’t do grim. He does nerdy, optimistic, heart-wrenching problem-solving . And in Project Hail Mary , he delivers a masterpiece.
