Despite her monstrous appearance, Iris has never felt like she belongs in a mansion filled with kelpies and gorgons and unicorns. She longs to find a family. Unfortunately, she and her housemates are trapped in a “foster home for horrors” run by former paranormal investigator Mr. Halloway. So, when a human boy named Mathias breaks the house’s sealing spell, Iris and her companions are set free upon the town of Dead End Springs.

What Iris doesn’t know is that Mathias is also a paranormal hunter (the kind who seeks to capture and destroy the horrors), or that there are other dangers ahead. As Iris searches for a home, she makes human friends, explores a brand-new world…and stumbles upon a dark secret that Halloway has kept locked in the basement of the house. Will this long-slumbering mystery destroy the family Iris so desperately seeks?
