Welcome to the intricate, disquieting world of the Bird twins, where one sister’s lies send the other back into their dangerous past.

When Kat Bird wakes up from a coma, she sees her mirror image: Jude, her twin sister. Kat remembers nothing except Jude, who must take on the momentous task of rebuilding their past block by block. But as the months progress, Kat begins to fear that, maybe, their childhood wasn’t nearly as idyllic as Jude wants her to believe―a realization that threatens their bond, their safety, and even their lives.
