Mockingbird

11-year-old Caitlin has Asperger's syndrome, and has always had her older brother, Devon, to explain the confusing things around her. But when Devon is killed in a tragic school shooting, Caitlin has to try and make sense of the world without him. With her dad spending most of his time crying in the shower, and her life at school becoming increasingly difficult, it doesn't seem like things will ever get better again.
