Williams portrayal of Galen is what makes this book. Around the standard "go and fetch this and kill the villain" quest story, we are given an extremely amusing antihero narrator. Galen is intelligent, mercenary, and a coward. He'd sell his own grandmother if he could find her.
This makes a nice change from all the whiny, holier than thou heroes which seem to plague the rest of Dragonlance (Tanis for instance). Granted you can still hear the dice rolling in the background, but Galen is so likeable that it doesn't matter. And he's likeable because he really is everyman, a hero who would much rather lay around and do nothing than be out adventuring.
If you like your heroes with sarcasm, darkly horrid (but not evil)back story and other touches of reality, this is the Dragonlance book to get. If you like your heroes whiter than white, find another book.
