Father Figure — Richard Peck

Running scared and talking glib, seventeen-year-old Jim Atwater has played father to his kid brother, Byron, since his parents' divorce eight years ago. But their ordered world falls apart when Jim's mother dies -- and his father turns up out of nowhere for the funeral. Soon Jim and Byron are going to "nowhere" themselves, on a plane to Florida to live with him for the summer. Can Jim set aside his anger and come to terms with his father?
