Nothing's set in stone. To fates unknown.
The Hollow Hills are an underground railroad for Monsters. Created by Witches and Warlocks as slaves, they rose up and displayed more humanity than the humans who'd made them.
We focus on the Sparcs- a 'Spectrally Protective Agency Restricting Casualties'- a police force of part-time exorcists, deputized Bogeymen and women hunting down human predators; practically a supernatural SVU, Monsters under the bed locking up those atop it; the Big Bad Wolf arresting Ted Bundy, so to speak.
A horror parody of children's fantasy adventure novels, intended for adults who grew up with such books, although the main characters are kids, a reader's heart equally rests with their parents, who've risked life and limb to shelter their charges from the more mundane monsters they'd grown up around.
So, stick around in turn, and read along as one form of predators hidden in human skin hunt another.
