This book is one part Gossip Girl and one part I Know What You Did Last Summer, without all of the gore, of course. It's got the expensive clothes and snobby behavior of the Upper East Side with a dash of mystery and suspense from old secrets. And, to my surprise, I really enjoyed it. There are a lot of books that run in the vein of the pretty and popular getting what's coming to them, and this isn't exactly that. The four main characters are all described as pretty, of course, hence the title, but they aren't all the most popular girls in school. They are all the kinds of girls you could pass in the hallway, though, and think they have picture-perfect lives.

Spencer is the golden girl, always in the advanced classes and squeezing in as many extracurricular activities as possible—whatever will look good on her college application. She also lives permanently in her big sister's shadow and keeps falling for the wrong guys.

Aria has just moved back to Pennsylvania after living with her family in Europe. She's artistic and not all that interested in being popular, having finally found out who she wants to be. She's also having an affair with a teacher.

Emily has always been the model daughter, following the rules of her strict parents, swimming her way to a college scholarship, and dating the perfect guy. When a new family moves in to what used to be Alison's house, though, she starts to question what it is she really wants.

Hannah is the new queen bee. She's the kind of girl guys want to date and girls want to be. What no one knows is that her ultra slim figure is the result of a disgusting habit stemming from all of her insecurities, or that her mother pays more attention to her work than she does to Hannah.

Part of what makes the book so great is how different from one another these four main characters are. It's kind of difficult to imagine that they were ever best friends, especially since they rarely interact throughout the novel. Not until the very end do all four of them appear in the same place, and when they do, it's easy to understand how they were so close once, but also how they all drifted apart. It's also a good thing that I went in to this book knowing it's the start of a series, because the ending really leaves you hanging. Almost nothing of the big mystery is revealed, but I don't mind because it gives me the excuse to check out the next book, which I will definitely be doing.
