Halloween is drawing near and Ally is far from the safety of Troutespond. Her attempts at a normal life have netted her a role in a cursed-to-die orchestra club, haunted by its past members. Now, unwittingly tied to thirteen musical ghosts, the more they play, the more their fates are bound to the dead. With the help of Alana, her boyfriend the Piper, and the new friends she's made on campus, Ally must find a way to break the curse, while trying to be a model student, girlfriend and mandolin player.
