Query: A note from the author...

I have read this book over ten times, and I continue to find it interesting, entertaining, and thought-provoking. This could largely be because I am the author, and I have very bad short-term memory. But just the same, I know that if I can read it several times without being bored, then all of you will enjoy it as well.Those of you who are not too keen on science fiction should also give Zero Calvin a chance. While the storyline mainly takes place in the future, you will find that most of the concepts are presented in a plausible, reality-based manner (with the exception of the ones that are made in jest.) This is not a fantasy book, but it does have many imaginative and funny concepts within its pages.-Brian Cramer
