Grubbs Grady leads his team in pursuit of the Lambs, demonic sheep that may have information about the Shadow's army, and battle other demonic beings along the way.
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.
With the opening of a window into a demon world, a boy discovers his powers as a Disciple and his mission to hunt the viciously powerful Demonata to the death.
As Be'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.
Grubbs Grady has defeated demons and managed to move on with his life, but strange symptoms during the full moon show him his dark days are not over--and he may not be able to fight his werewolf genes.
