When Kol Bennett is found after eighteen months of being missing, everyone is expecting her to name the monster who took her.
The only problem is that she can't remember who did it.
Diagnosed with retrograde episodic memory loss, Kol can't remember anything- not even her own name. She doesn't know her family, her friends, or the boy who says that they were secretly seeing each other before she went missing.
Then she gets a note from the person who took her, telling her that they're waiting for her.
With no memory, a boy who says that he's there to help, and clues left in a diary she didn't know she had, Kol has to race against the clock and find out who took her before they can fulfill their promises and find her again.
