Honestly, it dpends on you. There is not really a straight answer to this question. Read the book "Stick and Rudder" then re-read it. To study for you FAA practical, I would recommend a Gleims to pass the knowledge test. Then the Pilots Hanbook of Aeronautical Knowledge is another one that you should read. Any FAA book is a good book to read, but it can get overcomplicated and that is why there are many many many other books out there. This is from my expereince and my study habits that I have found this out, so yours might be different. My best advice, start with with a few from different sources (ASA, Jepp, FAA) and see which ones allow you to get the most out of them. It might be a bit more expensive, but it is well worth it and it allows you to save money in the long run for your ticket. Hope that helps.
