We Were Liars, by E. LockhartRead about the other entries on the list.
Lockhart creates a tightly woven narrative about a girl, her family’s island, and a troupe of lying cousins. This is one of those books you shouldn’t know anything about before you start reading, so I won’t summarize it here, except to say the threat is mainly psychological, and Lockhart does a fabulous job of building tension in each scene. That tension leads to a twist ending that will blow you away.
