The visitors from downriver had strange pale skin & blue eyes, but they left a deadly sickness of red spots & fever. Thirteen-year-old Millie & her younger sister Maura were the only survivors. As the first snowflakes fell the dogs were turning wild, & it was clear that the two girls must leave to find a new home. They loaded up a raft to take them away, & so began an epic journey through the harsh snowy landscape. This is an extraordinary story of courage, commitment & survival.
