Death in the Dark Woods by Annelise Ryan

A potential Bigfoot sighting is linked to a vicious murder, but skeptical cryptozoologist Morgan Carter is on the case in this new Monster Hunter Mystery by USA Today bestselling author Annelise Ryan.
Business has been booming since Morgan Carter solved the case of the monster living in Lake Michigan. The Odds and Ends bookstore is thriving, of course, but Morgan is most excited by the doors that were opened for her as a cryptid hunter.
Recently, there have been numerous sightings of a Bigfoot-type creature in the Chequamegon-Nicolet National Forest area of Bayfield County, Wisconsin. After a man is found dead from a vicious throat injury in the forest, the conservation warden asks Morgan to investigate.
When Morgan and her dog, Newt, go there to investigate, they uncover a trail of lies, deception, and murder. It seems a mysterious creature is indeed living in the forest, and Morgan might be its next target.
