There are lots of books and resources to study in order to become a pilot. You could spend a couple hundred dollars on textbooks, the most relevant being:

Airplane Flying Handbook
FAR/AIM
Pilot's Handbook of Aeronautical Knowledge

Aviation Weather


Alternatively, you could take advantage of them as free resources compiled and provided by the FAA. I've taken the liberty of compiling links to the most relevant information required on your pilot journey.
