Pretty Little Liars is an American teen drama mystery/thriller television series based on the popular series of novels written by Sara Shepard.
Set in the fictitious town of Rosewood, Pennsylvania, the series follows the lives of Spencer Hastings (Troian Bellisario), Hanna Marin (Ashley Benson), Aria Montgomery (Lucy Hale) and Emily Fields (Shay Mitchell), four girls whose clique falls apart after the disappearance of their queen bee, Alison DiLaurentis (Sasha Pieterse). One year later, they begin receiving messages from a mysterious figure using the name "A" who threatens to expose their secrets. At first they think its Alison herself, but after she is found dead, the girls realize that someone else knows their secrets—including long-hidden ones they thought only Alison knew.

I love this show!!! It is really fun to watch and the books are great too. Sometimes they can be a little over-dramatic. But isn't that the whole fun?
