Hands-down the best book on writing I have read. You'll want to be familiar with Moorcock's work before jumping in, however. That doesn't mean you need to have read all of his work (good luck on that one!) but some familiarity with the Elric series and at least one or two others does help one to synthesize all the information. Read carefully, though, and you'll find that this is really a writer's manual cleverly disguised as a series of entertaining interviews. You won't find this one cheap,but if you can get a copy, it's worth the price.
