RaveBookreporter... a combustible, hair-raising thriller about not-so-nice girls ... I could not have prepared myself for how downright chilling this book is. Flynn is an expert in adolescent psychology and female friendships, and her descriptions of mean girls doing bad things are nearly unparalleled. The thriller genre has exploded with villainous female protagonists over the last few years, and though I’ve read similar premises, Flynn makes the college setting feel fresh and original. By using one of these mean girls as her main character, she ups the ante in shocking ways. What was so absolutely tantalizing about the book was how effectively it played upon the desires that every teen girl has: to be liked, to make friends, to matter.
