The fourth novel in the Seasonal Quartet by Man Booker Prize Finalist Ali Smith is "a prose poem in praise of memory, forgiveness, getting the joke, and seizing the moment" (The New York Times). In the present, Sacha knows the world's in trouble. Her brother Robert just is trouble. Their mother and father are having trouble. Meanwhile, the world's in meltdown--and the real meltdown hasn't even started yet. In the past, a lovely summer. A different brother and sister know they're living on borrowed time. This is a story about people on the brink of change. They're family, but they think they're strangers. So: Where does family begin? And what do people who think they've got nothing in common have in common? Summer.
