This is among the most enjoyable Salvatore books that I've read, and in my view is definitely the best of the Sundering era. The action is fast, furious, and epic. While other books have featured exciting, small squad skirmishes, this one gives us those as well as epic battles for the fates of cities. On top of the battles, we are treated to reconnaissance, espionage, and another hearty helping of political machinations among the Drow.
Regis, who in many ways was the star of The Companions, took something of a back seat in Night of the Hunter. In this book, however, he was back to playing a central role, and in my view has easily become the most dynamic and interesting character in the crew. Furthermore, while Jarlaxle spent Night of the Hunter reacting, in this book he seems to be back on the offensive. As we might expect, of course, exactly what he's after still has yet to become clear. Beyond those two, I'm not sure that we see a lot of significant character development, aside from some continued discussions between Drizzt and Catti-brie on the inherent nature of orcs and goblins.
I really enjoyed the book, and will, of course, look forward to reading the next in the series when it is published in 2015.
