The fact that he has a quote from Jim Butcher would have sold me on this book. I found it browsing through Goodreads. And a wonderful find it is.
The description made it sound a lot like Jim Butcher's books, so I was curious how Connolly's world would compare. Very different. There are similarities, in the same way that any urban fantasy must have - real-world people unused to magic, practitioners of magic that go dark and a ruling body that says who gets to use magic.
The plot is fast paced and the minor characters have adequate depth. I like the main character, Ray Lilly. He changes, almost against his will over the course of the book. It's a matter of regaining a moral compass. He doesn't necessarily want to be a better person, but he knows he has to. I will definitely read the rest of the series.
So Harry, write faster!
