Twiceorphaned Sylvi has chipped out a niche for herself in Layce, an island cursed by eternal winter. Alone in her truck, she takes comfort in two things: the solitude of the roads and the favor of Winter, an icy spirit who has protected her since she was just a child. But when her best friend, Lenore, runs off with the rebels, Sylvi finds herself making a haul too late in the season for a smuggler whom she wouldn’t normally work with, the infamous Mars Dresden. Alongside his team—Hyla, a giant warrior woman, and Kyn, a boy with skin like stone—Sylvi will do whatever it takes to save her friend. But when the time comes, Sylvi will have to choose: safety, anonymity, and the favor of Winter—or the future of the island that she calls home?
