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.
Hey did you see the new episode of Pretty Little Liars?

Yeah, but I can't believe that they figured out Ali was dead in the first episode. That's not supposed to happen until later. The books are way better/

Unlike the series, the definition of Pretty Little Liars is quite simple. This is a tight-knit circle of friends who always share secrets and plan to keep them. Even under the watchful eye of any adult these girls will lie through their teeth to get what they want. To be like these girls, you need to be gorgeous, a great liar, and most important: secretive.

"I know. What a group of liars."
