One of those hideous books where the mother dies: Sonya Sones

This was teen fiction and a bit predictable, but still good. A 15 yr old's mother dies from a disease and she is forced to live with her father whom she doesn't know. Her aunt has taken her to see her father at the movies because he is a movie star. So she knows who her father is, just doesn't know him. Her aunt sends her to Hollywood and she is appalled by how big her father's ego is. She also has culture shock and is very different from the students in her school. She keeps in touch with her best friend and boyfriend from back home, but when they start dating each other she falls into depression. Ruby's only friend is Max, a friend of her dad's...who also ends up being her father's boyfriend. After a few months she finds the good in her father and forgives her best friend and starts to make a new life for herself.
