I am listening to the audiobook of The Black Company right now (I have read a couple of the stand alone novels in the past, but never managed to get to the original novels), and it is the most D&D fiction I have ever encountered. It could straight up be a 1E campaign diary (except, you know, it's good).
What fiction have you encountered that was not branded D&D fiction that gave you the sense that it was, in fact, D&D fiction?
Difficulty: you can't choose anything from Appendix N or, really, anything from before D&D existed. No inspirational works, just things that have come out since and give you the "that's D&D" vibe. Also, it doesn't matter if it's good or not.
