Thirsa and the Ghost Plane

Thirsa's parents are divorced. Now "uncle" Walter and his annoying son Theo suddenly live with her. Thirsa misses her father and her sweet, forgetful grandmother, who sometimes thinks the Second World War isn't over yet. During the war, Grandma lost the love of her life, which still saddens her sometimes. Thirsa and her two best friends—the funny Joep and the smart Eric—devise a plan to make Grandma happy again. The three friends unintentionally end up in a turbulent adventure that involves not only the Second World War, but also a magical drawing pad, a ghost plane, and a tough girl who wants to be a pilot.
