by Andy Weir opens with a classic science-fiction scenario: our hero wakes up in a blank hospital room surrounded by machines, and he has no idea who he is or what he’s doing there. It turns out that figuring out these existential black holes in his memory is key to his mission to save Earth from alien microbes that are dimming the sun. The book is a sci-fi puzzle, and, like Weir’s predecessor The Martian, is tailor-made for a big-screen adaptation. Word has it that the movie is already on the way!
