CRIMINAL MIND | PRETTY LITTLE LIARS

It's been one year since Alison DiLaurentis - the queen bee of Rosewood High - went missing. Spencer, Aria, Hanna, and Emily have tried to move on with their lives, though they've grown apart. Now, in their final two years of high school, each girl faces a new set of challenges when anonymous text messages from "A" threaten to expose all their secrets - both the ones they thought only Alison knew and the new ones they've kept since her disappearance.

Who is "A," and how does this person know everything about them?

But Alison's friends aren't the only ones guarding secrets in Rosewood.

Sana Reed - the girl who knows all, with a criminal mind built to uncover and bury lies - has her own motives. She's willing to tell the truth, but only on her terms. And not everyone in Rosewood is ready for the conditions she sets.
