Problem: The Xanth series is what got me reading sci-fi and fantasy novels. Its a shame this series has turned into unreadable mush.Zombie Lover was the last book I've bought in this series and I don't think I'll continue with it. I can't take in anymore stories of adolescents thinking about who they want or don't want to have sex with.
Solution: Negative
