The Colour of Magic by Terry Pratchett

Okay so I love Rincewind. He is like the best wizzard I have ever read about. Yeah you're right, there ain't actually that many wizzards floating around are there. But, there are a lot of wizards and he is better than all of them. This book is amazing. Rincewind lives through every single situation put to him. The tourist Twoflower and his luggage (with thousands of tiny legs) (soon to be Rincewind's luggage) are the best companions you could ever imagine.
