Classical Guitar Online Lessons Academy

I just bought a classical guitar. I only want to play bossa nova and samba. I know I need to learn the basics. I just ordered Hal Leonards guitar method. Is there a book strictly for bossa nova beginners? Where is it? Or do I have to learn from someone?

From what I know this may be your best bet:
