Four Pretty Little Liars still haven't learned their lesson....

In idyllic Rosewood, Pennsylvania, nothing is quite as it seems....

Fifteen years ago an anonymous tormentor known only as A terrorized Emily Fields, Spencer Hastings, Hanna Marin, and Aria Montgomery--watching their every move, revealing their darkest secrets, and even nearly killing them.

Now A is in jail and the Pretty Little Liars have grown up and moved on. Emily is happily married. Spencer is on partner track at her law firm. Hanna's family is the envy of the neighborhood. And Aria is a finalist for a coveted art fellowship.

Their lives are perfect. Or so they say.

Turns out, Emily is hiding a big secret from her wife. Spencer has used some dirty tricks to claw her way to the top. Hanna's family isn't nearly as perfect as it seems. And Aria will do anything to win that fellowship.

After all, once a liar, always a liar. And guess what? A is still watching....
