For nonfiction, I like books on history (any period at all) and Christian doctrine. For fiction, I used to be almost exclusively a sci-fi and fantasy reader; but starting something like twenty years ago, I began being more open to conventional stories, including Westerns. Of stories I myself have written, the two that I consider my own VERY best works are stories rooted in the known world. Both of these can be found right here, in Professor's Writing Club. One, "The Tale of Sophia Renee," is a love story set in Victorian England. The other, "The First Love of Alipang Havens," is what they call a "coming-of-age" novel. Its hero is a Filipino orphan boy adopted by Americans.
Note that on the SAME thread as my "First Love" novel, I am currently writing a sequel, titled "The Possible Future of Alipang Havens." It is a science-fiction novel by necessity, since it projects what experiences Alipang and the Havens family might have in the year 2025.
