Sofia Bottom lives in Elysia, a small country forgotten by Europe. But inside its borders, the old myths of trees that come alive and faeries who live among their roots have given way to an explosion of the arts and the consolations of philosophy. From the clarinetists to the cabaret singers, no artist is as revered as Sofias brilliant mother, the writer Clara Bottom.

When the countrys greatest enemy invades, and the Capital is under threat, Clara turns to her daughter to smuggle her new manuscript to safety on the last train evacuating children from the city. But when the train draws to a suspicious halt in the middle of a forest, Sofia is forced to run for her life and loses her mothers most prized possession. Frightened and alone in a country at war, Sofia must find a way to reclaim what she has lost.
