What can I say about it? Though how come that wizard got so many spells to cast without resting is beyond me, this is a part of a D&D game in book form, just like most in "Forgotten Realms". Not a lot of literary value, but an easy read if you know what it's all about. Also, I guess it does help when all characters are supposed to be evil; none of their action can disappoint you.
The events are on a greater scale than in the first of this series, at least.
