Growing up, goody-two-shoes Kirra Jacobs and troublemaker Reef McKenna were always at odds. Now paired together on Yancey's search-and-rescue canine unit, they begin to put aside old arguments as they come to see each other in a different light. Then a call comes in from the Iditarod that will push them to their limits.
Kirra's uncle, a musher in the race, has disappeared. Kirra and Reef quickly track the man, but what they discover is harrowing. Frank's daughter has been kidnapped. In order to save her, the man must use his knowledge as a mechanical engineer to do the kidnapper's bidding or she will die. Kirra and Reef, along with the entire McKenna family, are thrown into a race to stop a shadowy villain who is not only threatening a girl's life, but appears willing to unleash one of the largest disasters Alaska has ever seen.
