Sisters in Sanity by Gayle Forman

Summary: "When a family trip to the Grand Canyon turns out to be a trick to take her to a remote, all-girl, residential treatment center for unstable teenagers, sixteen-year-old Brit, devastated by her father's duplicity, comes to realize that only through inner strength and the help of other inmates who become her friends can she endure the harsh conditions of the prison-like institution and plan a way to escape."

I really enjoyed this book - it's short and sweet. The friendship and sisterhood of Brit and the girls she meets at Red Rock is quite refreshing.
