After angering a local gangster, seventeen-year-old Sena Korhosen must flee with the gangster's prize fighting wolf, Iska, in tow. A team of scientists offer to pay her way off her frozen planet on one condition: she gets them to the finish line of the planet's infamous sled race.
Though Sena always swore she'd never race after it claimed both her mothers' lives, it's now her only option. But the tundra is a treacherous place, and as the race unfolds and their lives are threatened at every turn, Sena starts to question her own abilities. She must discover whether she's strong enough to survive the wild-whether she and Iska together are strong enough to get them all out alive.
