Winter Study (An Anna Pigeon Novel)

It's January and Park Range Anna Pigeon is sent to Isle Royale in Lake Superior to learn wolf management. She's lodging in the island's bunkhouse with the famed wolf study team, and two scientists from Homeland Security, who are considering opening the park in the winters, so that the area can be manned to secure border with Canada -- bringing an end to the 50-year study. Soon following Anna's arrival, the wolf packs under observation begin to behave oddly. The discovery of wolf scat containing alien DNA leads the group to believe that perhaps a wolf-dog hybrid has been introduced to the island. But when a female member of the team is savaged, Anna realizes that something is seriously wrong. Now, what was once an idyllic refuge becomes a place of imminent danger. Without electricity or running water, and with temperatures hovering around zero, Anna must fight for her life;
