The Blood of a Dragon - Ethshar, Bk 4 Author:Lawrence Watt-Evans This is the story of a lad named Dumery of Shiphaven who desperately wants to be a magician, but has no talent for magic at all. The best apprenticeship he can hope for, he decides, is to become one of the people who supplies the wizards with dragon's blood -- and that doesn't work out too well, either.
