If Morning Ever Comes Av Anne Tyler

Ben Joe is at college studying law when he gets a letter from his family saying one of his six sisters, Joanne, has returned home having left her husband, bringing her baby with her. Ben Joe goes home, and when he returns he remembers the past, the death of his father, his first girlfriend. He visits his father's girlfriend and then his own ex-girlfriend, Shelley. Shelley now has a boyfriend, John, but they see each other anyway, and in the interim, Joanne starts seeing John, until her husband turns up to take her home. Ben Joe asks Shelley to go back with him and marry him, so once everyone has got back to the way they were, he heads off to college again, with Shelley.
