Among the mystery books I've read, which are mostly whodunnits, this is the first police procedural novel. As expected, it describes the criminal case as close to reality as possible, including the police routines (which is tense, rather stressing and a bit dull, in my opinion), crime scene technicians in action with the gunpowder test, taking fingerprints, etc. and the judicial process. All of them are fairly new concepts for me to find in a novel. And since the writer is a former policewoman herself, those concepts can be conveyed in a great detail yet easy to understand.
For the characters, I think Deb Ralston is a good combination of 'cold' logic and 'warm' emotion. I also enjoy the psychological journey of Olead Baker, from a schizophrenic to a man being able to love.
Great premise. Great characters. Great book.
