Caitlin is an eleven year old girl with Aspberger's syndrome. She struggles in school, and her only friend is her older brother, Devon. But Devon is killed in a school shooting, and Caitlin must learn to navigate the world - and school - on her own.
Caitlin's dad is completely devastated after the shooting and provides little help to her. Her mom died years earlier from cancer, so her source of aid is the school counselor, Mrs. Brook. Through her, Caitlin learns about empathy, friendship, and gaining closure.
I liked the strong message of this novel and thought that Kathryn Erskine did a terrific job of showing exactly what the mind of someone with Aspberger's looks like. I also loved the allusion to How to Kill a Mockingbird (you'll have to read the book to figure out how they're connected!). However, I didn't really enjoy the novel that much. It didn't hold my attention - I often caught my mind wandering as I read.
