Tolkien reader here since I was a kid. All the rest of the authors you listed...whoa, I haven't heard of any of them...and I'm a reader! At least, I thought I was lol. Are those fantasy authors? That could explain it. I haven't read a lot of fantasy but I have some. Nada Lada christian fantasy at all in fact. I was heavy into science fiction for the longest time, before I found the book of books! Mostly Heinlein, Bradbury, Asimov and others. Can you recommend any especially good books by any of the authors you listed?
The ones I listed are mostly fantasy Christian writers and Heinlein, Asimov et al I'd call science fiction. Madeleine L'Engle is the only one I'd call sci fi out of that bunch and I loved
A Wrinkle in Time. Of the rest I like Shawn Lamb the best because he is more historical fiction along the lines of a Bernard Cornwell (Sharpe series, etc) and coming from Huguenot stock I really liked the Huguenot Sword and appreciated the human face it put on my ancestors for me. Craig W. Dressler has fantasy books he's written, but my favorite book of his is
Heart of Terror that reads more like a Jack Reacher or Scott Horvath novel.
