I appreciate fiction, but I almost always read nonfiction. It’s probably because I typically choose the books on topics I’m interested in, and I want to learn about them. But I also love the way a great nonfiction writer can weave a narrative so strong that it’s just as much literature as it is journalism.
Some of my favorite examples of nonfiction that do this well: Soul Full of Coal Dust, Toms River, Desert Solitaire (Abbey can be problematic, though, so be warned), The Pine Barrens, This Land, and on and on.
I guess I’m kinda stuck in the environment/nature section these days!
It usually doesn’t give me any trouble. I have run into issues where I was reading non-fiction about the Napoleonic Wars and also a historical fiction book about naval warfare during the Napoleonic Wars. As one might guess, I had trouble remembering what actually happened and what was fiction. As long as I avoid situations like that I’m usually okay, hah.
