Summary: Jocelyn's twin brother Jack was everything she had growing up in a world of foster homes - and now he's dead, and she has nothing. Then she gets a cryptic letter from "Jason December" - the code name her brother used to use when he made up elaborate puzzles to fill the unhappy hours at Seale House, a terrifying foster home from their childhood. Only one other person knows about Jason December: Noah, Jocelyn's childhood crush, and their only real friend among the troubled children at Seale House. But when Jocelyn sneaks off to return to Seale House and the city where she last saw Noah, she gets more than she bargained for. Turns out Seale House's dark powers weren't just the figment of a childish information. And someone is following Jocelyn. Is Jack still alive? And if he is, what kind of trouble is he in - and how can Jocelyn and Noah help him?
