Silas's life is spiralling out of control when he receives an invitation from Eve to trek the Tasmanian wilderness, with a disclaimer: It will be cold. Remote. Treacherous. And I cannot guarantee passage home alive. The trek is a sheer vertical climb. In Antarctic conditions. Subject to violent storms. Untamed, unpeopled and dangerous. Also, exactly what Silas needs to reset his compass. But then a polar blast hits. Perilously cold and cut off from help, Silas and Eve face a stark, gale-forced world. And one terrible choice. Choices are not always easy, even when they're right. But Silas has never shied away from making tough decisions. Until now. Until this. Because this is the most brutal survival lesson. And sometimes the cost of saving a life can only be measured by the cost of losing one.
