This is a great book to start inking with. It walks you straight through all sorts of things to practice, starting with materials and how to make a line to how to produce different types of images using different techniques. Also a good reference for how to render different textures if you are already more experienced. And the more newbie information would be a good refresher when you are burnt out.
