Who wrote the pretty little liars book series? Rules: You only get one chance to answer. I'll give you a clue: It's either out of the following Sara Shepard Marlene King J.K Rowling Suzanne Collins

Alright, process of elimination is needed here.

Suzanne Collins can be crossed out; I've read her books, which is the trilogy of The Hunger Games.
We all know J.K Rowling wrote the Harry Potter books, so I think she can be crossed out, unless she's wrote other books on the side... (not counting the books within the Harry Potter books)

I think for a guess, I'm gonna go with...
Sara Shepard.
