Fiction novel w POV switch between siblings

It is fiction and switches points of view between three siblings, two being sisters and the third being the brother.

The book starts with a car crash caused by the brothers intoxicated girlfriend, which causes a small child to die and the girlfriend goes to jail. The book follows the three siblings for the next fifteen or so years. One sister is a lesbian in an off and on relationship, one gets a divorce, and the brother becomes an addict, eventually dying because of it. I remember the girlfriend of the sister is a nurse/model named maude and the brothers girlfriend is named Olivia. What book am i looking for?
