I’m hoping to find a book I read scores ago. Teenage girl with a punk rock/rock best friend (Renee?) and this guy who liked her possibly unofficial boyfriend. One day she sees her dad with another woman. She follows him one day and calls his office and the Secretary mistakes him for the other woman and jokes with her before putting the call through to him. I thought it was called Daddy’s Girl but nothing comes up with that name (that would be considered YA) The cover was a girl ina denim jacket watching a couple from a distance on a sidewalk in front of a store.
