"Mockingbird" by Kathryn Erskine-- 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.
