WTF. What a horrible book! What an amazing book! 
 This review can also be found at BookShelfery.Whoa. This book is one twisty, didn't-see-THAT-coming, mind blower! 
 But let's rewind and start at the beginning. The Liars: Cadence Sinclair Eastman, her cousins Johnny and Mirren, and Gat, who is the nephew of her aunt's boyfriend. The Liars spend summers on their family's private island near Martha's Vineyard. Young, wealthy, and carefree, life is nothing but fun for the cousins. Until the summer they are 15, that is...then everything changes. 
 We meet Cady when she is 17, going back to the island for the first time since that summer. She doesn't remember what has happened, she only knows that it's something so terrible that it has changed who she is - once strong, blond, and beautiful, she is now weak, dark, and suffers terrible migraines. No one on the island will talk to her about the accident, or incident, or whatever it was. But slowly her memories return and she begins to piece back together the events of Summer Fifteen. 
 I was a little skeptical to trust Cadence as a narrator -after all, she is okay with the label of Liar. We never find out exactly why the aunts gave them that title, just that they probably deserved it. I really liked the fairy tales Cady wrote along the way that gave us tiny glimpses of insight. And even though the Sinclair family is ridiculously wealthy, the author has managed to make some of the characters real and flawed and likeable. I could relate to Cady and Gat in their all-consuming first-summer-love excitement, and I was cheering for them even though their relationship didn't seem likely to last outside of the island. 
 We Were Liars by E. Lockhart is a book you won't be able to put down. I read it in one sitting - thank goodness for long car trips! This is the perfect summer read. And that, friends, is all I can tell you. So go quickly, before someone spoils it, and discover this for yourself!
