There is a great book called, experience, and that you cannot buy from amazon. You feel your code is clunky because of lack of design. And lack of design comes from the fact that we usually don't know what we want to design till we design it. This is where prototypes come in handy because prototypes shed the light on problems that we didn't foresee. Rule of thumb for prototype code is to throw it away once you are done. What I am trying to say here is that you don't need a book to learn what you are asking for, you need experience.
