An Enchantment of Ravens and was everything I wanted in a faye romance novel. I was rooting for the couple the whole time and the faye rules were super interesting - a little spooky, a little funny, magical and elegant. They had the usual rules of magic of faye that one is familiar with, re: lying, social constructs, etc.
The magic system is really interesting, too, that Craft is something only humans can do and therefore faye covet. It's a cool base concept, and one that is woven throughout and not just forgotten after the beginning.
