I first came to this #bookmatch when considering books with cults--Delicious Foods (which I promise I will stop posting about) isn't EXACTLY a cult per-se...but then I saw the #evilkin prompt and thought that could work too. It's not exactly kin in DF, but people (or substances) that pretend that level of closeness... In the end, these books have numerous points of comparison but pretty different moods/effects, which I always find interesting.
