I had a ball reading this book. It's a great read, filled with wit, humor, and insight. The surprises come non-stop, from first chapter to last. Although quite frightening in places, the uplifting message more than compensates for the nail-biting. Suspense and satire blended into a terrific thriller. And there are enough pearls of wisdom here to keep philosophers occupied all winter. Certainly one of the most enjoyable novels I've read in a long, long while.
