@TheRedGambit My choice of history books vary, depending on what I find in bookstores. Sometimes I peruse the bibliographies of books I read, to see if something catches my attention.

But the topic I've read the most about is World War 1.

I'm not too keen on reading outside history genre. I did enjoy some historical fiction though: A Gentleman in Moscow (Amor Towles), The Historian (Elizabeth Kostova).

But roughly 90-95% of what I read in a year are history books.
