A long, cold winter in Alaska promises nothing good. Caught in a snowstorm, Liza McCall, an inventor, disappears without a trace. Leaving everything behind, her older sister Abby flies in from England to join the rescuers. It has been four years since the terrible quarrel, and she hasn’t spoken to her sister—yet now it suddenly becomes clear that they probably won’t have a chance to make peace. Alone in a freezing watchman’s hut, Abby, fighting her own personal drama, does everything she can to figure out how and why Liza vanished. And soon she understands that it’s far worse than it seems. But if she wants to survive, she’ll have to get to the truth. Translation from English by Nikolay Kolevich.
