Jeffery Russell's The Dungeoneers:Blackfrog Island brings back some of the funniest fantasy I've read!
When you need someone to fetch a missing prize from a deep, dank, dark dungeon you call the Dungeoneers. The gang of steel nerved dwarves and their odd-ball accompaniment are back, this time headed to Blackfrog Island! Pirates, the high seas, and zombie rats await our team of deep-dungeon-explorers as they attempt to brave a mysterious island from which no one returns.
I really enjoyed Russell's first installment as well.
