Good Morning, Midnight follows two characters in a post-apocalyptic world: an aging astronomer named Augustine (Clooney) who is trapped in the Arctic, and an astronaut named Sullivan on her way back to Earth. The official synopsis for the book is:
Augustine, a brilliant, aging astronomer, is consumed by the stars. For years he has lived in remote outposts, studying the sky for evidence of how the universe began. At his latest posting, in a research center in the Arctic, news of a catastrophic event arrives. The scientists are forced to evacuate, but Augustine stubbornly refuses to abandon his work.
