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 fellow housemates are trapped in a "foster home for horrors" run by former paranormal investigator Mr. Halloway. So when a human boy named Mathias manages to break the house's locking spell, Iris and the other monsters are set free upon a town of Dead End Springs. Finally, a chance to find a real home! 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?
