I have started playing chess a few months back and I am certainly enjoying my time on chess.com. I am really a beginner in chess and I also learned castling a while ago which I had no idea existed in chess but now I know pretty much all the basic stuff in and I was wondering what are some books that will improve my game and teach me openings and other things that I should know?
