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/

A show that you both love, and love to hate. It's so addicting and entertaining, but it drives you crazy. And now it drives you more crazy because Keegan Allen figured out who A is. None of your non PLL watching friends get your obsession with the show. PLL=Pretty Little Liars
Conversation with a friend who watches PLL
Friend: Do you watch PLL?
You: Hell yes!
Friend: Do you know who A is?
You: No, please tell me! Tell me! TELL ME! (Suddenly realize you're friend doesn't know who A is.)

Conversation with a non PLL watching friends:
Friend: What shoes are you wearing to prom?
You (thinking, this is my chance to quote Hanna from PLL): I wear three inches or I wear nothing.
Friend (confused and looking at your sneakers/other casual shoe): Since when?
You (thinking, Spencer quote time): And this is relevant to this conversation because...
Friend (even more confused): WTF? You aren't making sense!
You (thinking, Alison quote time): Sometimes a lie is more interesting than the truth.
Friend (coming to a look of understanding, it's not like she's escaped hearing about the show that much): For the last time stop quoting Pretty Little Liars (she doesn't know the abbreviation)! I don't even watch that show!
You: Hmmph!

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!
