The Invention of Lying
After living his whole life as a loser in an alternative universe where no one has ever told a lie (consequently making them aggressively, nastily honest), Mark Bellison transcends reality by discovering how, in his words, to "say something that wasn't." This leads to a spree of Groundhogs Day style indulgence of wealth, power and sex. But after he comforts his dying mother with the made-up fantasy of a pleasant afterlife, all the humans of the world demand to know more. Bellison soon discovers that answering the world's questions about life, death, morality and true happiness are more difficult than he'd thought: even with the power of unquestioned lies.
