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/

An ABC Family series. The show is based around 4 bestfriends who started getting creepy texts signed 'A' a year after their 'leader' Alison goes missing. Alison was the most popular, and prettiest girl at Rosewood High, but she was actually a bitch who made fun of everybody. She believed in that secrets brought people closer, and therefor knew all of Aria's, Spencer's, Emily's, and Hanna's secrets. And after mysteriously disappearing a year ago, the 4 besties get texts from an all-knowing A who knows their dark secrets, blackmails them, and seems to know exactly what their next move will be. They cannot go to the police about A, because A knows things that they don't want the police to know. This show is the perfect dose of romance, humor, mystery, and suspense. It's pretty addictive.
Friend: Yo do you watch PLL?
Me: Hell ya! It's the best show ever!
Friend: What season is it on?
Me: Season 5! And we're supposed to finally find out who A is at the end of Season 6! I love Pretty Little Liars!

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."
