Mockingbird (mok'ing-burd) by Kathryn Erskine

Caitlin's world falls apart the day her brother is shot and killed in a junior high school shooting. As a child with Asperger's her brother was her link to the world. He helped her cope with school, clothes and behavior and since her dad is drowning in his own grief Caitlin looks in books and her dictionary for help. She figures out that what they need is some sort of closure to help put their lives back together. This is a remarkable book which lets us get inside Caitlin's head and understand a little more about people with this syndrome. Mockingbird by Kathryn Erskine is a quick enjoyable read.
