The plot - a little girl thinks that she is 9? Years old. She lives with her dad and mom, an aunt, and a mean (girl) cousin a little older than her. Later on, it turns out that she is actually about 12 years old, but she was raped at 9, and her parents suppressed the memory of the rape by making her think that she was younger than she was. At the end, it turns out that the mean cousin (who is actually her half sister) orchestrated the rape. I may be a little unclear about the ages, but does anyone remember reading a book like this? It's driving me crazy that I can't remember the title.
