Query: Author overboard

Witless and unrelievedly dreadful. So bad it could have been the basis for a late 70's Disney movie. I've found more convincing plots and more compelling characters on the backs of cereal boxes. Even a "no-star" rating would be too high -- Amazon should have a "black hole" rating for books like this one.
