While I've been a member here on bitcointalk and a miner for quite a long time now I just recently picked up Phil Champagne's "The Book of Satoshi." I have began reading this book but I have also read Nathaniel Popper's book "Digital Gold" which is really good.
the most important think you need to read is "how to secure your wallet" , this is an article tho, so you don't need to pay any cents, but really helpful compared to another article even books
