There is no perfect drawing manual that'll magically make you a good artist if you follow it closely enough. It's about putting in the time and work and having some guidance to help you try out different things. You can read a few pages from one manual, follow it a bit, then try another, but ideally, you'll spend most of your time drawing, looking at references (whether photo or life) and drawing even more.
What do you even want to draw? Have you tried drawing it? What are your results? See anything that bothers you? Fix gradually, try drawing easier things and don't think you need to do everything at once, it's a process.
