Beginning in the summer of 1939, fourteen-year-old Jacob Koopman and his older brother, Edwin, enjoy lives of prosperity and quiet contentment. Many of the residents in their small Dutch town have some connection to the Koopman lightbulb factory, and the locals hold the family in high esteem. On days when they aren't playing with friends, Jacob and Edwin help their Uncle Martin on his fishing boat in the North Sea, where German ships have become a common sight. But conflict still seems unthinkable, even as the boys' father naively sends his sons to a Hitler Youth Camp in an effort to secure German business for the factory. When war breaks out, Jacob's world is thrown into chaos. The Boat Runner follows Jacob over the course of four years, through the forests of France, the stormy beaches of England, and deep within the secret missions of the German Navy, where he is confronted with the moral dilemma that will change his life-and his life's mission-forever.
