When Detective Nick D'Artori arrives at the scene of the Troll-Killer of Portal Park’s latest attack, he knows his night isn't going to be boring. Finding the Troll-Killer's victim alive—if missing one of his two heads—seems like a stroke of much needed good luck. But why would the victim, a royal guard, have wandered away from his duty? And was it only coincidence that the Troll-Killer happened to target him? The inconsistencies lead Nick and his partner, Renee Arbors, down a new road of investigation, but they’ll have to negotiate it while foiling mad bombers, carjackers and trollish magic.
