Josie and Jack: A Novel - Kelly Braffet Josie and Jack are being raised by a professor father, who acts like he's mad. They have never gone to school and have always each other's companion. Jack manipulates Josie into situations and then turns on her and anyone else who is around. She's hanging on to her sanity by the skin of her teeth.

Really good book, has a taboo subject that may turn people off but it's not written in nitty-gritty detail. This did not feel like a Young Adult book at all.
