While enjoying a rare weekend off from her duties as an agent with the Investigative Services Branch, Felicity Harland learns that a young couple has turned up dead in Gates of the Arctic National Park. Harland recruits her partner, ex-Navy SEAL Ferdinand "Hux" Huxley, to join her in the investigation. After processing the peculiar scene where the couple perished, Harland and Hux decide that this was no tragic accident. They soon hear about a man living off the land, recruiting couples to his "fertility cult" in the Arctic. Could this survivalist have played a role in the couple's death? Determined to get to the truth before anyone else meets a similar fate, Harland and Hux venture deep into the backcountry to find the cult's campsite. But what they find there tests their relationship in ways they never imagined--and thrusts them into a dangerous and deadly game.
