Sarah has always been on the move. Her mother hates the cold, so every few months her parents pack their bags and drag her off after the sun. She’s grown up lonely and longing for magic. She doesn’t know that it’s magic her parents are running from. When Sarah’s mother walks out on their family, all the strange old magic they have tried to hide from comes rising into their mundane world. Her father begins to change into something wild and beastly, but before his transformation is complete, he takes Sarah to her grandparents—people she has never met, didn’t even know were still alive.
