I have to say, I have two of Saliba's books, and I don't find them useful at all. Options workbook 3rd Ed and Option Strategies for Directionless Markets I think reading the other books mentioned covers in greater detail what they attempt to teach you. I feel like these books are for people who want something quick and basic to go learn to trade. But IMO, they leave a lot of unknowns, mostly about pricing model, the assumptions behind the pricing model, and some additional theory.
this was an excellent book! though should you decide to purchase it, go to nuclearphynance forums for the errata. It's under the books section.
