When a new strain of the deadly drug, Redrum creates UV resistant vampires, the streets of New York City are flooded with the mindless creatures searching for blood—human blood. The NYTF and Dark Council refuse to deal with menace and contact the Night Wardens expecting results. What they get is a dark mage with nothing to lose. Now Grey Stryder-a dying dark mage and rogue Night Warden must join Koda, a short tempered, trigger-happy assassin to clean the streets of New York, find the source of Redrum, and keep humanity off the menu, before it’s too late. Together they will be become the heroes the city needs-but no one wants.

Sometimes fear of the dark can keep you alive. Grey and Koda have a lead on the supplier of Redrum X—a new strain of the deadly drug that creates UV resistant vampires. Preventing the streets of New York City from being flooded with the mindless creatures was only the first step. Each night as darkness falls, body counts rise. Someone or something has made nights in the city…fatal. Grey must find who or what is doing the killing and stop them. He only has one clue. Rumors of a Mr. Dark are being whispered in the streets. Is this Mr. Dark responsible for the deaths? Now together with Koda, Grey will enter a world no Night Warden has encountered. A world of darkness no one has escaped. Can a dark mage wielding a darker blade bring light to save others?

The Tenebrous has been eliminated, but that’s only the beginning of Grey’s problems. When Koda is taken by rummers during a routine night patrol, Grey knows their behavior is anything but routine. Rummers don’t kidnap their victims—they consume them. Now, Grey must discover who or what is controlling these creatures of darkness, producing and flooding the streets of his city with Redrum X, and stop them. Or die trying. Getting Koda back will force Grey to face enemies in the shadows. Enemies that prefer to hide in the dark. They will soon realize that Night Wardens not only dwell in the darkness—Night Wardens thrive in the darkness.
