She's Come Undone

Summary of the book so far- From what I have read so far is that there is a girl named Dolores whose parents are divorced after her mom lost a baby because of a miscarriage. She never gets over this and creates her "angel" that she always talks to. After a couple of years she should be over it, but she's not. Then a new couple moves to the apartment above them, and the whole family loved them. After Dolores becomes friends with the guy Jack he starts taking her home from school everyday. One day he made a detour and ended up rapping her, and now she doesn't know what to do.
