Seventeen-year-old Sena Korhosen hates the sled race, especially after it claimed both her mothers' lives five years ago. Alone on her frozen planet, she makes money any other way she can—until she double-crosses a local gangster. Desperate to escape, Sena flees with his prized fighting wolf, Iska, and takes an offer from a team of scientists. They'll pay her way off-world, on one condition—that she uses the survival skills her mothers taught her to get them to the end of the race. But the tundra is a treacherous place. When the race threatens their lives at every turn, Sena must discover whether her abilities are enough to help them survive the wild, and whether she and Iska together are strong enough to get them all out alive. As the girl and the wolf forge a tenuous bond and fight to escape ice goblins, giant bears, and the ruthless gang leader intent on trapping them both, one question drives them relentlessly forward: Where do you turn when there is nowhere to hide?
