This is book 2 in the Guardian Series. Based on a recommendation from the author, I started reading the Guardian Series with book 3, and read and really enjoyed the series. So I decided to go back, and pick up the back story with book 1 (which is not available on kindle!!!) and book 2. Book 1 was rather long and convoluted, but Demon Moon was very much like the rest of the series, and I really loved it. While you could probably skip book 1 completely, there was actually alot in there that I thought directly fed into this story.
This was a beautiful story, but one of the things that I really loved about it was the non-standard characters. The heroine is half Indian, and the hero is vain and selfish. Meljean Brook has a habit of populating her books with interesting characters from all places and times, and it makes for a refreshing read.
