fox-moon and angelfire are two good sites for information. Dragon Magick though is not a religion, it's a path to more powerful magic and balance within yourself. so most people couple it with a religion. if you follow Wicca, then add it into your beliefs, but there's no books for 'Dragon Wicca' i'm afraid.
