Pratchett and Gaiman bring us a funny book about The End Times. As Armageddon draws near, at least one of the angels and one of the devils have lost a bit of enthusiasm for the fight of good vs. evil, and would really rather see the world continue on its way. So they set about scheming to prevent the apocalypse as the Son of Satan is born in England 11 years before he is prophesied to bring about the end of the world. 
 There were lots of funny moments here, and I should also give due credit to Martin Jarvis in the audio version for the character he injects in the characters with his performances.
