Once a year in the woods outside Ember Grove, the Revelry occurs. Everyone knows what it is -- an exclusive, mysterious party in the woods at the school year's end. But nobody really knows what happens there. Because once you attend the Revelry, you are sworn to secrecy... forever. Bitsy Clark knows better than to break the rules around the Revelry. But her best friend, Amy, isn't waiting for an invitation. As the night comes closer, her plan is clear -- she and Bitsy are going to sneak their way in. Bitsy can remember being nervous about this. She can remember going to the woods. But after that: Nothing. She doesn't know what happened to her. All she knows is that her life starts to unravel, while Amy's good fortune grows stronger. Has Bitsy been cursed? And if so, will she be able to discover enough secrets of the Revelry in order to free herself?
