I didn't know his kid was a writer as well.
For fiction I used to be super into high fantasy - LotR, Wheel of Time, and many others. Dresden Files was not something I had ever been interested in - urban fantasy always felt low-brow, but I loved it and am glad I gave it, and that genre a chance.
I definitely read more nonfiction these days. The real world is so full of fascinating topics I know little or nothing about, it seems endless.
