Years of covering the antics of End Times cults for The Banner, a religious news magazine, have left Christine Temetri not only jaded but seriously questioning her career choice. That is, until she meets Mercury, an anti-establishment angel who's frittering his time away whipping up batches of Rice Krispy Treats and perfecting his ping-pong backhand instead of doing his job: helping to orchestrate Armageddon. With the end near and angels and demons debating the finer political points of the Apocalypse, Christine and Mercury accidentally foil an attempt to assassinate one Karl Grissom, a thirty-seven-year-old film school dropout about to make his big break as the Antichrist. Now, to save the world, she must negotiate the byzantine bureaucracies of Heaven and Hell and convince the apathetic Mercury to take a stand, all the while putting up with the obnoxious mouth-breathing Antichrist.
