Query: The best of the series

I have read the first 17 or so books in the Xanth series and nothing compares to this title. I would rate all the books including Night Mare and back to "A Spell for Chameleon" 5 stars, but after that the series gradually declines in value. I believe the reason for the degradation of interest in Xanth is that the landscape becomes less lethal in the latter books. In "A Spell for Chameleon", all off Xanth's fuana and even its flora represents a potential threat, and it makes the book more suspenseful. It could be read alone with out interest in future Xanth books and the final chapter wouldn't leave you hanging, yet it still leaves behind an interest in what future holds for Bink, the main character. A Spell for Chameleon is definitely one of the best titles there is in the Xanth series, and perhaps one of the best books I have ever read.
