Killer by Sara Shepard
Gossip thrives amid the Mercedes-Benzes, mega mansions, and perfectly manicure hedges in the exclusive town of Rosewood, Pennsylvania. Everyone has something to hide, especially high school juniors Spencer, Aria, Emily, and Hanna.
I tried but couldn't find a synopsis for Killer, so this will have to do. I am currently reading Perfect, the third in the series and am completely in love (I started the series two days ago!) The intriguing mystery mixed in with the chick-lit atmosphere produces a compelling guilty pleasure series. Killer will be released on June 30, 2009. (I've heard there will be 8 books in the series...yay!)
