Laptop of the gods - Peter Chippindale

It is December 1999 and, as the millennium approaches, all is not well in the Land of the Gods. The deities, engrossed in their petty squabbles, are bored out of their immortal skulls with the hapless earthlings in their charge. So when GOD, the central computer running the universe, offers them the alternative of endless virtual reality games in Mega Retroland, they jump at the chance to shrug off their responsibilities forever. While GOD continues to send streams of inconsequential e-mails, it seems only mighty Jupiter, and his equally powerful consort Juno, are left to care about the disintegration of mortal society. Until Cupid hacks into GOD's mainframe and uncovers a sinister plot, masterminded by the Beast in the Machine.
Suddenly the race is on. Are the gods doomed? Or can they fight back in time to save not just themselves, but all of us on Planet Earth?
