Cut by Patrica Mcormick is a very good book. The Back of the book says
"Callie cuts herself. Never to deep, never enough to die. But enough to feel the pain. Enough to feel the scream inside. Now she's at Sea Pines, a "residential treatment facility" filed with girls struggling with problems of their own. Calie doesn't want to have anything to do with them. She won't speak to anyone. But Callie can only stay silent for so long......" I have read this book at least 15 times and i am still loving it. So read it.
