This will be random, but I've always have had the sick thought about writing a book like ones about Madeline visiting Washington D.C. or America which turns into one where she is an orphan girl who grows up in a Paris which is under the control of a victorious Greater German Reich and has to go visit the Fuhrer in a ceremony at the Volkshalle in Germania. We see European life in such a way as she travels from Paris to Germania making observations along the way such as seeing slave laborers in the street cleaning, riding the Breitspurbahn, where British and French people are forced to work in German factories. She might even visit a German colony on the eastern front to see how its expanding.
Something to be thought to provoke to young people and semi-realistic.
