Detective Carson O'Connor is cool, cynical, and every bit as tough as she looks. Her partner Michael Maddison would back her up all the way to Hell itself, and that just may be where this case ends up. For the no-nonsense O'Connor is suddenly talking about an ages-old conspiracy, a near immortal race of beings, and killers that are more, and less, than human. Soon it will be clear that as crazy as she sounds, the truth is even more ominous. For their quarry isn't merely a homicidal maniac, but his deranged maker.
