Mostly Harmless

Just when Arthur Dent makes the terrible mistake of enjoying life, all hell breaks loose. The guide reports that it has a lot to say on parallel universes. This info, however, is not much understandable to anyone under the level of advanced god, and since all known gods were made within 0.333 milliseconds of the creation of the universe ( Not last week, like they always say) they are therefore not available for comment right now...
Arthur finds himself in a parallel universe where the Earth has been replaced with a planet called Nowwhat, and immediately escapes it by unkown means. If you want to know the conclusion to Douglas Adam's Hitchiker trilogy read this book now!!
