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?
