Interestingly, I just read today a book by Carol Alexander called Market Models. It has an excellent discussion of volatility in it along with a bunch of models to estimate it. I was seriously impressed as she adresses some issues for options traders. It may not be what you're looking for though as it isn't a trading book.
Other than that google for an online copy of Coulda, Shoulda , Woulda by Cottle. His original one was called Options Pereception/Deception, but it isn't available.
