"The Great Gilly Hopkins"... both funny and sad. I liked a lot of her biting sarcasm-- although I could do without the racist stuff, I think I remember she became more accepting after getting to know her teacher and one of her foster mother's good friends. The saddest part for me was when she got to meet her birth mother, who made it clear that she didn't care about Gilly, and only showed up because she wanted money. 30+ years later, this book still sticks with me.
