It should have been the perfect summer. Sent to stay with her late mother’s eccentric family in London, sixteen-year-old Joan is determined to enjoy herself. She loves her job at the historic Holland House, and when her co-worker Nick asks her on a date, it feels like everything is falling into place.

But she soon learns the truth: her family are monsters with terrifying, hidden powers, and Nick is a legendary monster slayer who will do anything to bring them down. As she battles Nick, Joan is forced to work with the ruthless Aaron Oliver, heir to a monster family that hates her own. She will have to embrace her own monstrousness if she is to save herself and her family. Because in this story, she is not the hero.
