This club was named, "The Churchill Club," and the brothers along with eight boys targeted homes, offices, and stores of Nazi sympathizers vandalizing them. They left a calling card in blue paint whenever they struck. The club included about ten passive members that supported them with supplies and money, but who stayed out of the action. Their actions became bolder committing arson and stealing weapons from German solders before getting caught and sent to prison.
The story reads like a narrative from Knud's point of view. Text boxes containing facts, maps, primary photos, and Knud's sketches add to the depth and richness of the story. I read this on the Kindle and I would have probably preferred the book. The separation of text features is limited in space on the Kindle as it only shows one page at a time. I got the idea and saw the separation by a bold black line but I had to enlarge the photos to see some details and the maps were unreadable unless enlarged. You might want to consider what format you want to use when reading this book. A fascinating look at children making a difference in the world.
