After Nazi Germany invades and occupies Norway, 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, he 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.

Preus incorporates archival photographs, maps, and other images to tell this story based on the real-life adventures of Norwegian Erling Storrusten, whom Preus interviewed in Norway.

"Preus deftly uses together historical fact (Espen is based on a real-life spy) and elements of Norwegian culture to conjure a time and place not so terribly long ago." --Wall Street Journal

"Engrossing . . . This is at once a spy thriller, a coming-of-age story, and a chronicle of escalating bravery. Multidimensional characters fill this gripping tale that keeps readers riveted to the end." --School Library Journal (Starred Review)
