In the shadows of Nocturne City, witches lurk and demons prowl, and homicide detective Luna Wilder must keep the peace—while living life as a werewolf. Now bodies are turning up all over town, the brutal murders linked by a cryptic message: We see with empty eyes...

To make matters worse for Luna, she can't get wolfishly handsome Dmitri Sandovsky out of her mind. The last time he helped her with a case, Dmitri suffered a demon bite that infected him with a mysterious illness...and now his pack elders have forbidden him from associating with Luna. But she'll need his help when high-level witches start turning up slaughtered. Because a war is brewing between rival clans of blood witches and caster witches—a magical gang war with the power to burn Nocturne City to the ground.
