Never trust a pretty girl with an ugly secret.

Suddenly, their picture-perfect world begins to unravel as lies and betrayal threaten everything they hold dear. . . including their lives. Based on the popular book series, Pretty Little Liars by Sara Shepard.

A popular book series by Sara Shepard about four pretty little liars, Aria, Spencer, Emily and Hanna, who have shared a secret since 6th grade... a secret they thought was safe forever. Then the girls start recieving threatening text messages signed by some mysterious person called "A"- Someone who knows everything about them. Suddenly, their big secrets- the ones only known by their dead best friend Ali- are not so secret. Suddenly, nothing in Rosewood is safe.

An amazing and captivating book series by Sarah Sheppard. The books are not only filled with amazing plot and suspense but are also quite addictive. However, this book series (like many others of its kind) was completely butchered when it arrived on the TV. Not only did ABC family completely mess up the character's appearances (which threw avid PLL fans off) but they also made major changes to the plot that completely ruin the storyline.
