Query: The is one of the worst SF novels ever.

It is not so much because of this book, but because of the series that follows that I gave this book such a poor review. This book, bursting over with some of the smallest-minded puns imaginable is a work of what I believe is Science Fiction's Horatio Alger.Piers Anthony relies upon the hormones of his teenage audience when he writes in the sexual innuendo that has been one of the main reasons for the success of his novels.Furthermore, this novel, like all Piers Anthony novels, has a very easily predictable plot (it would be nice if the hero didn't always get laid by the end of the novel).Look, for all you young Science Fiction fans out there, the 11,12,13 year old guys who just starting to really get into this genre, stay away from this guy. You'll regret ever picking up one of his novels in your 20's (heck I sure do).
