When our main character dies, she wakes up on a ship to Elsewhere, where all dead things go. Once there, everyone ages backwards, getting younger as the years pass. When they reach infancy, they are sent back to live again as someone new.
This story is so awesomely new. The quote on the front jacket from the New York Times Book Review states: "Every so often a book comes along with a premise so fresh and arresting, it seems to exist in a category all its own." To which I can only reply, "Ditto."
