A quest, a puzzle, and multiple lives: On an artificial world with a forgotten past, floods of "silver" rise in the night like fog, rewriting the landscape and consuming those caught in its cold mists. Seventeen-year-old Jubilee knows that no one ever returns from the silver--but then a forbidding stranger appears, asking after her beloved brother, lost long ago to a silver flood. Could he still be alive? And why does the silver rise ever higher, threatening to drown the world? Jubilee pursues the truth on a quest to unlock the memory of a past reaching back farther than she ever imagined.
