An enormous axe-wielding woman shows up on Ray's doorstep. She's a stranger, and she refuses to share her name. All she'll say is that she was sent to protect Ray. What from? The Axe-Woman doesn't know, but she's not about to let Ray out of her sight.

As Ray navigates her neighbourhood with this unlikely body-guard in tow, she's not always sure who's protecting whom. But it soon becomes alarmingly clear that the danger is very real, and that if Ray wants to keep herself and her friends safe, she'll have to figure out the mystery of the Axe-Woman's identity.
