Harry Bodie's been called into the delightful fantasy world of his grandmother's beloved children's books. It's not delightful here at all. All roads lead to Underhill, where it's always winter, and never nice. Harry Bodie has a famous grandmother, who wrote beloved children's books set in the delightful world of Underhill. Harry himself is a failing kids' TV presenter whose every attempt to advance his career ends in self-sabotage. His family history seems to be nothing but an impediment. An impediment... or worse. What if Underhill is real? What if it has been waiting decades for a promised child to visit? What if it isn't delightful at all? And what if its denizens have run out of patience and are taking matters into their own hands?
