'When Treghan, Corilai, Marni and Fletcher travel to the icy mountain city of Windwall to study under the city's rangers, they find themselves thrust into the mystery of a rumoured gang of criminals hiding in the blizzard covered peaks. Children have been kidnapped, young people are disappearing, and there have been a string of brazen thefts from the local landholders. With the situation looking perilous, the four are ordered to remain inside the city walls. Sometimes, things happen that force a person's hand. And when those orders must be broken, it results in a perilous journey through ice and wind into the heart of the Everwinter Highlands. Can they save those who have been taken, before it is too late?'
