Chrissie is eight and she has a secret: she has just killed a boy. The feeling made her belly fizz like soda pop. Her playmates are tearful and their mothers are terrified, keeping them locked indoors.

People are looking for them, the past is catching up, and Chrissie fears losing the only thing in this world she cares about, her child.
