A lot of ppl like Kathy Liens “day trading the currency market”. I feel a lot of that book applies to swing trading also. I would read and learn a lot about price action. You’ll need a lot of books not just one. Get some on trading psychology, some informing you about the markets you’re interested in FX, some with systems. Books will only take you so far, after learning a lot of it is practice and time. But books can give you a foundation.
