The Price of Power? GreyHawk Lore

Doing some real light reading of late. I'm reading "The Price of Power" by Rose Estes. The story is set in the Dungeons and Dragons Greyhawk campaign setting. Maelfesh the demon attempts to take revenge on Mika for taking down Iuz. Seems kinda of odd, far as I can tell everyone takes down Iuz eventually in Greyhawk. Mika, the protagonist, has to find away out before Maelfesh grows tired of him and ends him.

The best part so far? Mika's wolf gets turned into a wolf-troll. No more spoilers. Promise. ;) What's your favorite part?
