Mockingbird by Kathryn Erskine

From the Publisher: "In Caitlin's world, everything is black or white. Things are good or bad. Anything in between is confusing. That's the stuff Caitlin's older brother, Devon, has always explained. But now Devon's dead and Dad is no help at all. Caitlin wants to get over it, but as an eleven-year-old girl with Asperger's, she doesn't know how. When she reads the definition of closure, she realizes that is what she needs. In her search for it, Caitlin discovers that not everything is black and white—the world is full of colors—messy and beautiful."
