This is undoubtedly one of the most hilarious and down right eccentric books in the Discworld series. This isn't the best place to start for newcomers to the series as it relies heavily on you liking books like The Colour of Magic, The Light Fantastic, Eric, Sourcery and any book that has the complexities of magic and Rincewind, and this book is an extreme. It asks about philosophical impossibilities and theories of time and matter fitting into itself!? It's definately a very plot filled book. It follows the adventures of the misplaced Rincewind(and the Luggage), the misplaced Unseen University seniors(who run into a deity who hasn't quite learnt about "the birds and the bees") who are looking for him, and the Librarian(who, god forbid, is sick). It's full of brand new and crazy characters, who all reside in Continentia Incognito, the Last Continent, which Rincewind has to save and is , as ever, running away from. If you thought some of the earlier Discworld books set around wizards were to eccentric this isn't for you, but give it a try anyway I'm usually wrong on peoples opinions.
