Ideally, I would like you to go read this book right now without reading another word about it.
No? Still here? Fine. I'll tell you a little, but really - a librarian friend who read an advance copy of this told me to go into it blind, and that was really good advice. But if you must know, We Were Liars is the story of a teenage member of a rich New England family - like own-their-own-island rich - who has had something terrible happen to her. And really, that's all I want to say about the plot. I will say that the book has interesting characters, a very distinctive voice, fascinating structure, and all the trappings of a rich people summer house novel, which is a subgenre I love. It's a perfect summer read, captivating and mysterious. Oh, and if you can, clear out an evening, because you're not going to want to put this down once you start.
