Pitch Dark by Paul Doiron

When Hammond Pratt goes missing, game warden Mike Bowditch goes to investigate. Pratt had come to Maine from Idaho, looking for a man and his daughter who were living in the woods. The man, Mark Redmond, is building a cabin near the Canadian border for a woman named Josie Jonson, who is close with Stacey (Mike's wife) and her father, Charley Stevens. The simple act of finding a missing person leads Mike on a trail of violence and murder, with even Mike himself fighting for survival. Pitch Dark is similar in format to Doiron's Dead by Dawn. It will be published next month.
