Aria Montgomery and her friends; Hanna Marin, Spencer Hastings, and Emily Fields are liars. They've lied about almost anything possible to stay safe. But with A after them, it's hard to keep secrets without someone; usually A... getting it out there. Since Alison; one of the girls' best friends died, their lives have only gone downhill. Threats from A, deaths of friends... None of it seems to end. But, what if it was all because one of them kept too many secrets? Aria has kept one of the biggest secrets of them all. One may have been one too many.
