Shadow on the Mountain paperback

by Margi Preus.
After Nazi Germany invades and occupies Norway, fourteen-year-old Espen and his friends are swept up in the Norwegian resistance movement. Espen gets his start by delivering illegal newspapers, then graduates to the role of courier, and finally becomes a spy, dodging the Gestapo along the way. During five years under the Nazi regime, Espen, his sister, and their parents live in fear of nighttime raids and arrests, and they begin to question the loyalties of the people around them. Espen gains - and loses- friends, falls in love, and makes one small mistake that threatens to catch up with him as he sets out to escape on skis over the mountains to Sweden. A thrilling adventure based on the real-life experiences of a Norwegian spy during World War II.
