Amy and her best friends--the Posse--are at camp and they're bored. In the scorching summer heat, sparks start to fly. Clare and Amy might be best friends, but they're sniping as if they're enemies. Camp leader Bevan is singling Amy out for attention, and Clare is jealous. Amy is feeling reckless enough to do something major. In one night everything will change. Friendships will be tested and broken; careers will hang in the balance; and everything Amy knows about her friends and her family will be ripped away. What really happened when Clare disappeared that night? Who's telling the truth? And when things go too far, should you save your friends--or save yourself? This tale of girls pushing the boundaries is always sharp and sassy, often hilarious, and occasionally shocking--you won't be able to put this down.
