Thoughts on Mystical Dragon Magick by DJ Conway? I’ve heard a lot of positive and negative things about it and I’m not sure if it’s worth picking up to get into dragon magick.

After meeting my guardian dragon, I've been really keen on getting into dragon magick. However DJ Conway's work, the most reputable source on this type of magick, has a lot of conflicted opinions on not just her dragon series but her works as a whole. Would Mystical Dragon Magick and her other dragon-based books be worth purchasing, or is looking elsewhere a better idea?
