Nightglass is one of my favorite Pathfinder novels, but after reading this one I can't get rid of the feeling that the story of Isiem should have ended there and then. Don't get me wrong, it's a thrilling adventure... that reads exactly like that: an adventuring party's journal. While the previous book told a story of tragedy and redemption, Nightblade might serve as an inspiration for a great dungeon crawl. Introductory chapters that try to seam the two stories together feel totally disconnected from what happens next. I don't think we have a shortage of unlikely parties going for a desperately dangerous quests in the series, and I am disappointed to see the author using her obvious talent to make another one.
