Dana Kane, the Area Master of Michigan, knows how to handle a heavy workload. With monsters lurking at every turn, her hunting abilities have never been in such high demand, but the number of Hunters available in the area has never been lower. Iva Morrell, her rival out of Ohio, has been busy too, but not hunting monsters. She’s dedicated her time to recruiting Dana best and brightest. The allure of state-of-the-art gear and substantially higher wages has caused many to defect and left Dana in an impossible position. When a genetically altered Chupacabra targets a young child, Dana and her remaining squad go to Puerto Rico to root out the elusive beast and destroy it before it strikes again. But their efforts are made more complicated when Iva learns of their mission and goes on the warpath to upend them with dirty tricks.
