What if the worst version of yourself was the one fighting to be remembered? At Blackthorne Academy, students change overnight. Personalities shift. Memories disappear. And nobody seems to notice. When Elena Cross transfers to the academy after her sister's disappearance, she quickly realizes there's something deeply wrong with the school's mandatory therapy program. Because unlike everyone else... Elena remembers fragments. A voice that sounds like hers. Conversations she never had. And a boy with haunted eyes who keeps looking at her like he's already lost her before. Kai Mercer knows more than he admits, and the closer Elena gets to the truth, the more unstable her own mind becomes. But some memories are buried for a reason. And some versions of yourself should never be brought back.
