Mockingbird is a young adult novel by American author Kathryn Erskine about a girl with Asperger's syndrome coping with the loss of her brother.

She is awkward and pedantic, seeing things in black and white, and referring to her deceased brother as "Devon who is dead" when talking to her father.

Common Sense Media found the book to be "sensitive, captivating, and, just put simply, a great read.

"[4] Simon Mason of The Guardian thought that the author's "evocation of 'Asperger thinking' is impressive and sensitively managed, but such narrowing of the focus reinforces the story's programmatic nature" and concluded, "In the end, like Caitlin's drawings, Mockingbird is a neat outline in black and white.

"[5] Kirkus Reviews found that "Erskine draws directly and indirectly on To Kill a Mockingbird and riffs on its central theme: The destruction of an innocent is perhaps both the deepest kind of psychosocial wound a community can face and its greatest opportunity for psychological and spiritual growth.
