Tempest Phish, the man that luck forgot, goes through a harrowing transformation to become Earth's next Christ. That's right - Tempest is the next Christ, as in Jesus Christ. Only for some strange reason Heaven wants him dead. In the blink of an eye Tempest's world is chock full of angels, devils and other creatures that didn't exist yesterday. A Definitive Sin continues on where the Bible left off - the twenty-third chapter to the most unbelievable story on, above and below the Earth...Biblical mythology survives in the twenty sixth book, Stupid Planet. Earth is now a vague memory-destroyed countless years ago by Jesus' creepy younger Brother, Meseris (The Anti-Christ). God has packed up shop, Fate isn't on speaking terms with anyone and the Anti-Christ is feeling a little bit guilty about the whole 'reigning-down-with-the-Apocalypse-thing.' Now, in the surreal void of a leftover afterlife, Meseris and a cast of Generation-X celestials are about to try the experiment of life all over again...
