Id agree with Dark Jetzer. Without posting a spoiler, both books are good. ALOT of battle scenes, well done but after a while it seems a bit repetitive. The subplots of supporting characters is interesting (perhaps more so than the main characters) and the return of the Bouldershoulders is cool. And the bad guys are actually more than plot devices.
On the bad side for me, if you dont like an introspective Drizzt you may not like this book. Without spoiling anything I thought his self doubt was a bit overblown. /shrug. And the whole love fest of the five core friends sometimes is a little grating for me personally.
In some ways I like it better than Icewind Dale Trilogy. The pros outweigh the cons for me. Ill definately be buying the third volume when its released.
