One day, using the magical passage that will take him to Monstros City, Billy forgets to close the door to the crypt, and is followed by . . . Victoria. Oh, no. Victoria is Billy's neighbor, his constant shadow, and a huge pain in the butt. Worse, Monstros City seems to exaggerate the traits people have in Bradbury - and Victoria arrives in Monstros with something that Billy and Archebold name the Destructo Touch. Owlboy is supposed to protect Monstros City - but has he just introduced the agent of its destruction?
