The Day Our Parents Came Back: A Sitcom In A Book

This is my first foray into comedy. If you enjoyed Monty Python's Life Of Brian you might enjoy this. If Life Of Brian offended you, you should steer clear. It's an irreverent comedy based around the disturbing idea that close relatives might be watching over you from heaven and seeing things you'd rather they didn't see!
In this scenario a married couple who were both orphaned at an early age have been watched over by their respective parents. When both start having affairs the two sets of parents manage to persuade God to send them back to have a word! I hope the consequences strike you as hilarious, but once God gets involved so too do the forces of darkness, so called.
Is heaven so great? Is hell so bad? Is it all just a game? The book is cynical and at times philosophical, but I hope it's consistently amusing as that is its primary purpose. By the end the world will never be the same again and nor will heaven or hell.
