The Pretty Little Liars book series are my favorite books. I have read all 8 of the books, that follow four girls living in Rosewood, Pennsylvania. These four girls had an end of seventh grade sleep over with their best friend, Alison. Ali is manipulative and popular. At the sleep over, Ali disappears and gets murdered. In high school, when they've separated from each other, these four girls, Spencer, Aria, Hanna, and Emily are taunted by a malicious stalker, who goes by the name "A". "A" knows these girls' secrets, and blackmails them.
The series follows Spencer, Aria, Hanna, and Emily solving Alison's mysterious disappearance, and the suspicious stalker, "A". It had dramatic suspenseful scenes, and all of these books are page-turners.
The fourth book in this series, Unbelievable, is my favorite. In this book, one of the girls, Hanna, discovers who "A" really is. "A" hits Hanna with her SUV, causing her to not remember the important information. The book ends with an intense epiphany, and a tragic death.
I finished Unbelievable in only a couple of hours, I just couldn't put it down. I have decided to re-read this fantastic suspense novel by Sara Shepherd.
