Query: disturbing and moving

A rerelease of a book I read over ten years ago. This is a haunting story of a girl abused by her parents & the system for not being "normal" -- she's mute. The story follows her from a childhood most often spent tied to a tree like a dog, to her involuntary commitment in a state institution (circa 1950s?) that is abusive and degrading. Yet she survives w/ the help of herself and a few friends made along the way. Not an easy book to read but worth your time.
