Loved the book, it was a very interesting twist on the genre and a unique look into the development of a hero (anti-hero?) Kylar is a memorable character and many of the books characters have a strong impact. The series was better and better as it went on, and the conclusion was both believable and entertaining.
I have also given it to my wife to read (who also loved it) and her sister received it for Christmas and read the whole series in under 2 weeks because it was so good.
I definitely recommend this book. The character was interesting, and the premise was different from other books I have read. It is worth a read as I read lots of books and it kept my attention to the end (read it in less than a week). You could tell what was coming in parts, but the author still kept it interesting and had a few unique twists. Who knew angels could be so entertaining?
