Historical novels are a good genre. I like it when they mix in real people with the fictional characters.
in the Thrift Store yesterday, I picked up the definitive biography of Dietrich Bonhoeffer.
It was a huge thick book, with lots of glossy page inserts with photos.
I brought it up to the counter, and said “This man is my hero”
The proprietor said..”Take it. it is my gift to you!”
