Growing up, goody-two-shoes Kirra Jacobs and troublemaker Reef McKenna were always at odds. Now, working together as search-and-rescue for Alaska's arduous Iditarod race, a growing attraction seems to be forcing aside old arguments. Then Reef catches Kirra sneaking from camp in the middle of the night. 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. 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.
