Learned to read when I was three. My godparents were retired schoolteachers and loved having such a willing pupil.
After that we moved a lot and I mowed through every library available. Would get a few bucks from my grandparents when we went to flea markets and I would get more books that way. Around nine or so I would get adult books on my father's library card; history and biographies and science, still favorite categories. For me, it's easier to get good nonfiction than good fiction.
In fiction, I read almost everything except romance and "women's novels"; military stuff does not interest me except in a history or thriller context; mainstream and literary fiction has this terrible tendency to be plotless and boring - pages of navel gazing does not interest me. I love thrillers, mystery, detective, horror, and science fiction the best.
Anything has to be written really well for me to enjoy it. Since I am also a writer, I can't handle bad styles or stupid plotting. That is when I bail early, like the book I tried recently where the author used up their lifetime quota of exclamation marks in the first three chapters.
Thanks for telling us more about your reading history, loves, and dislikes. You seem to have a pretty diverse interest. Keep up the great reading and writing.
