Oh, Mythology 101! I am very fond; it's fluff, but it's entertaining fluff with a good premise. There are three sequels; I quite liked Mythology Abroad, in which Keith and Holl take a trip to Ireland to find their respective Irish relatives and some magically significant flowers. I don't remember much about the other two; I don't think I found them as interesting, and I know there was some romantic drama in the fourth book that I found really irritating. But I still find Keith and his struggle to help the elves very endearing.
