Winter Camp (Hardcover, Turtleback School & Library ed.)

Recently orphaned, Toughboy and Sister live with Natasha, an elderly, cantankerous Athabascan Indian. In late fall she has them all flown to camp in a bush plane to teach the children how to trap and deal with the Alaskan winter. When an old miner is seriously injured and Natasha sets off for help, the children find their spirits pushed to the limits. Sequel to Toughboy and Sister.
