Good Omens as a story is a solid idea on its own, but it is thoroughly elevated through the collaboration of these two authors.

Little do they know that an accidental switcheroo left the infant Antichrist in the care of strangers. When Hell sets the Antichrist baby upon the world, marking the beginning of the end of days, the angel and demon strike up an unlikely bargain to keep Revelations from revealing itself.

Good Omens follows an angel and a demon, both of whom have spent a long time on earth and have grown accustomed to what the material world can offer. This novel, which tells the story of a bungled Biblical apocalypse and the hijinks that follow, was co-written by two titans of British genre fiction: Neil Gaiman and Terry Pratchett. * All two of them.For the most part, the fantasy genre has been defined by solo creators itching to plant their personal flags in the literary landscape-a divergence from that is what makes Good Omens so special. And if that isn't enough, they've still got Sunday to deal with. He's also totally invulnerable, and a nice kid. Because he's eleven years old, loves his dog even though it's really a Satanic hellhound under all that hair, really cares about the environment and is the sort of boy anyone would be proud to have as a son. Above all (or, in Aziraphale's case, below all) they need to find and kill the Antichrist, currently the most powerful creature on Earth.

So they've got no alternative but to stop the Four Motorcyclists of the Apocalypse, defeat the marching ranks of the Witchfinder's army* and - somehow - stop it all happening. They like it down here (or, in Crowley's case, up here). Which is a major problem for Crowley, Hell's most approachable demon and former serpent, and his opposite number and old friend Aziraphale, genuine angel and Soho bookshop owner. There will be seas of fire, rains of fish, the moon turning to blood and the massed armies of Heaven and Hell will sort it outonce and for all. Which means that Armageddon will happen on a Saturday night. According to the Nice and Accurate Prophecies of Agnes Nutter -the world's only 'totally reliable' guide to the future - the world will end on a Saturday.
