Cady: We Were Liars, by E. LockhartRead about the other entries on the list.
This is a tough one to talk about. Spoilers, you see. All I’ll say about this is that Cady’s recovering from a head injury and suffers from terrible migraines and memory loss, so her recollections of what really happened two summers ago is not completely reliable. But when you read this book, you’ll understand why—in some ways—Cady might just be the Katie Ledecky in the 800m freestyle of lying. This is a fantastically twisty, page-turn-y thriller. Go read it.
