When Moira Dreyfuss's parents announce that they're sending her to an all-girls boarding school deep in the Maine woods, she knows her parents are punishing her. She's been too much trouble since her best friend, Nathan, died-- and for a while before that. Moira soon learn that they're not so isolated after all: there's another, very different, Castle School nearby-- filled with boys whose parents sent them away, too. Exploring the schools will force Moira to confront her overwhelming grief... and the real reasons her parents sent her away.
