Pretty Little Liars - Overview

Overview

The series is loosely divided into three arcs of four to five books each, chronicling the introduction and reveal of each "A". The series follows the lives of four teenage girls;— Aria Montgomery, Emily Fields, Hanna Marin, and Spencer Hastings (nicknamed the Pretty Little Liars or simply the Liars) — whose clique falls apart after the disappearance of their best friend, Alison DiLaurentis. One year after her disappearance, they begin receiving text messages from an anonymous source, "A," who threatens to expose their secrets; including long-hidden ones they thought only their close friend Alison knew. But shortly after the messages begin, Alison's body is discovered. The books progress forward as the four girls try to figure out who "A" is.
