Query: Hoax is an appropriate title.

This book was not written by the person who wrote all previous Butch Karp novels. In this most recent book by Tanenbaum (which may actually BE by him rather than his ghostwriter Michael Gruber), the prose is hackneyed, the dialogue is stilted, the characters have no depth, I mean none-nix-zip-zero, and there are no contemplations, philosophical musings, or statements of sociocultural significance. It's not even worth buying to see what happened next to the individuals of the Karp family, because you can't believe that the characters in this book have any connection to the characters in previous books. Sorry.
