Secret Resistance (Revised Edition)

Secret Resistance is a children's book by Dutch author Beene Dubbelboer. Published in 1964, it was chosen as the best book of the year by the Rotterdam children's jury that same year.

The book describes the fate of a Drenthe border village during World War II, from the perspective of two friends, Wim and Geert. One day, they overhear a conversation between two Germans, which reveals that the Netherlands will be invaded the next day. They warn their parents, and indeed, the next day there's war.
The friends gradually become involved in all sorts of resistance activities: preventing goods from being requisitioned, sabotaging a traitor's car, and hiding paratroopers and a Jewish woman. Geert, Wim, and everyone who supports them do everything they can to protect the village and make things as difficult as possible for the Germans.
