Diamond has never known anything but death and destruction. An abandoned baby left to die, he was raised in a monastery and trained to kill. When his trainer pays him an unexpected visit in his native Hungary, Diamond is surprised to learn that he is needed in North America, where a curious and seemingly unstoppable force is at work. Sebastian Shade also fights vampires, but with a difference. He is one. Reformed by love experienced and lost some years before, Sebastian was urged out of his self-imposed hibernation and secretly recruited to help the Order of Destroyers fight evil. Now in present-day New York, he continues his work, along with his team of mortals. Diamond arrives in New York and goes straight to work, not knowing that Sebastian Shade is hunting the same villain as he. When they meet, it’s fireworks, and in more ways than one, when they finally come to the realization that if they are going to defeat this evil, they’ll have to do it together.

Diamond and Shade are together trying to manage their new relationship when suddenly there is a vampire in their city running wild, killing his victims, and carelessly leaving them everywhere. That is strange enough, but what is even stranger is that he seems to be a Destroyer, and he is connected to Shade. Diamond is aware of the love/hate history Shade has had with Destroyers, and he's none too happy about being confronted by one of Shade's past conquests.
