I tried so much to like that seriesHe's really good at description and setting things up, but if I remember right the bad guys were called something like Children of the Light? At the time I was reading it I was also in children's choir and we had a song about being children of light. I couldn't take it seriously anymore and laughed every time I read the phrase.
Yeah that's just one group of antagonists in the book. The books are really in depth so they aren't for everyone, but for me they were all worth it.
