Nora Macpherson is a rookie RCMP constable on her first assignment to Moose Forks, a ranching and logging community tucked into a wilderness landscape of snow-capped mountains, dense coniferous forests and glacial lakes and rivers. As one of the first-ever female Mounties, Nora must contend with the biases of some of her male colleagues as well as the social isolation of being a law enforcement officer in a small town. She befriends a young teacher, Abby Clarke, whose problem student, Tess Talbot, involves them in a search for answers to an old puzzle. Solving this mystery awakens Nora to the realization that there are many other unsolved disappearances haunting the northcountry.
