Query: A hard read, but an interesting one

How are 'angels' made? Is it perception? Chuck Baker, described as an angel of the Ottawa music scene, is also a serial killer. While he helps some young musicians, a particular few he keeps--and records their dying screams. What he unleashes from this is an Angel of Darkness--and an Angel of Pain. The book is eerie and somewhat wooden, but still a good, fast paced read.
