Olympic medalist Anna MacDonald comes home to Namekagon County to emcee the Great Wilderness Race as predators stalk the Northwoods. While occasional interactions with potentially dangerous animals are old hat for most residents, this changes when unpredictable behavior patterns make it unclear who is the hunter and who is the hunted. Sheriff John Cabrelli and the new Musky Falls chief of police work swiftly to keep the community calm as they try to piece together the clues before it is too late. Musky Run is the fourth book in the award-winning Northern Lakes Mystery series following Figure Eight, Spider Lake, and Bough Cutter.
