Espen starts by delivering illegal newspapers, but his responsibilities grow to more and more dangerous jobs. Based on real experiences of Norwegian Resistance workers during World War II, Shadow On the Mountain is an inspiring story of courage. It is a good introduction to the reality of World War II while remaining appropriate for younger readers. The adventures of Espen and his family focus more on resistance than violence.
