With superior worldbuilding, a relentless pace, a complex heroine, and a harrowing story that preys off of current events as much as its well-developed monster, this is a stellar horror novel that fires on all cylinders, from the first page through to its horrible conclusion. For fans of dark fantasy based on fairy tales such as Seanan McGuire’s “Wayward Children” series or novels by Helen Oyeyemi, with just the right touch of Sara Paretsky’s V.I. Warshawski.
