Karl May was a very famous German author. He wrote about his ficticious travels to North America, fights with and for American natives, travels to Turkey and the Near East, even to China. In real life, however, he spent a lot of time in jail and all his books are based on other peoples’ books.
As a kid, I read about 50 books by Karl May. And his texts are available online!
I think the mix of adventure and supreme moral values impressed as a kid, while I ignored the religious passages every now and then.
