This week is all about the show Pretty Little Liars. The show started out in 2010 with five best friends.  Alison DiLaurentis, the queen bee of the group, Aria Montgomery the artsy one, Spencer Hastings, the genius, Emily Fields the jock, and Hanna Marin, the "it girl".  The clique soon falls apart after Alison, the leader disappears. One year after her disappearance, the four girls start receiving messages from A, who threatens to expose their secrets.  At first, the think it is Alison, but they soon realize it isn't after her body is found.  The girls continue to receive more and more information from the mysterious A figure.  The whole point of the show is to figure out what happened to Alison, and to find out who is trying to expose their secrets. 
I would highly recommend this show if you are interested in mysteries, and like tons of suspense. It comes on every Tuesday night at 8/7c.
