Caitlin is a bright fifth grader and a gifted artist. She also has Asperger's syndrome, and lives in a world of her own. Her brother, Devon, was the one who always helped her get by. But a middle-school shooting took his life. Now she has only her widowed father to rely on, and he has problems — and grief — of his own. Can a wise school counselor help Caitlin reach out to a world she's never understood? With Devon gone, will she have the courage to live fully on her own? Caitlin's thought processes, including her own unique brand of logic, are the star of this breathtakingly original novel about the differences that make us who we are.
