This book was SO much better than I was expecting! One of my D&D games takes place in the Underdark so I read this to gain some knowledge. It's so well written. Great action scenes. The suspense of what was going to happen between two of the major characters I was rooting kept me on the edge of my seat. The evil matriarchal society was no joke. There are 38 books in the series. I might read a few more. SO GOOD! (TW for violence, mentions of rape.)
