Polar opposites, two nocturnals must overcome their differences and find a way to survive the blistering light and the engulfing night. Matthias is tranquil and drained of emotion and color. Frank is crass, boisterous, and as full of life as he was before the turning. One is a man without a past, and the other wishes he could forget his. Both are assigned to a strange murder case and must bring one of their own to justice to preserve the peace between the ruling corporations and the vampire council. But as the case turns deadly, the agents are forced to confront a talented young mage, a towering system of corruption, and their own selfish natures.
