Books help, but you can't beat the help of a GOOD coach particularly when you are starting. Books, like many coaches teach the opinion or fixation of the author or coach, which may be the current flavour but might not necessarily suit or work for every one. Fortunately most agree on the basic principles. Join a club, the NSRA club finder on their site will point you in the right direction.
Good shooting
