Pretty Little Liars

In the wealthy suburb of Rosewood, Pennsylvania, four teenage girls — Spencer Hastings, Hanna Marin, Aria Montgomery, and Emily Fields — were once part of an inseparable clique led by the beautiful and manipulative Alison DiLaurentis. But Alison disappeared one night, and the group fell apart.

Three years later, the girls have drifted into separate lives. Spencer is the overachieving perfectionist competing with her older sister. Hanna has reinvented herself as the new queen bee. Aria has just returned from a family trip to Iceland. Emily is the dedicated swimmer hiding a secret crush.

Then the texts start. Signed "-A," the messages reference secrets only Alison could have known. Someone is watching the Pretty Little Liars, and that someone knows everything.
