Presumably the only witness to the horrific and bloody murder of his entire family, a teenage boy must outwit not only the mental health professionals determined to cure his delusion, but also the demonic forces only he can see.

While on a horror movie set with his Uncle Dervish, Grubbs Grady realizes that his battle with the evil demon master Lord Loss may be about to resume.

When he begins experiencing alarming symptoms at the onset of the full moon, Grubbs Grady, who has so far escaped his family curse, fears that he is turning into a werewolf.

As Bec's relationship with Dervish improves, werewolves and demons attack and she sends Shark and Meera through a window to another universe to seek Beranabus, and soon all must face an even greater force of evil, the Shadow.

As the mysterious and sinister Shadow builds up an army of demons, Grubbs Grady and his friends search desperately for ways to combat its evil plot, but a new lead unexpectedly takes them to an old foe--the Lambs.
