Simon R. Greene's Nightside Novels

I've finished the first seven Nightside books by Simon R. Greene. Verdict: entertaining, although by the seventh book, Hell to Pay, they are getting a bit repetitive. The story arc of the first six books concluded, and the seventh is more of a standalone story. Greene raises the stakes and things get even more gruesome and dark. Not recommended for anyone offended by the notion of magic and evil powers that roam the night, but despite the grotesque trappings, Greene's world is actually rather mild, so I didn't hesitate to let Isaac read these. In Greene's world, while there a lot of dark forces at work, there is also right and wrong, even if the hero of the stories falls somewhere in between.
