Simeon Bell just hasn't been himself.Although he has spent a happy year as a roustabout with the Carnival of Mysteries-accompanied by his beloved, Crow Rapp-lately something has felt off. Maybe he hasn't been himself because he doesn't fully know who he is. Abandoned in a foundling home as an infant, he has never known anything about his family and has never met another of his kind.A tiny box found on the carnival midway leads Simeon and Crow on a quest to Simeon's childhood home in the Victorian slums of London, where he discovers the ability to move through time. With Crow's steadfast love as his anchor, Simeon searches across the decades for answers about his identity. The more he travels, the more he learns about his history¿ and the more he faces the danger of losing himself entirely.
