By day they lead ordinary lives, by night they hunt vampires. When JD agrees to train someone from outside the hunter society, little does he realise how much she will affect his life, and the lives of his fellow hunters. As she immerses herself in their world, she learns how deadly vampires are. Hunters have to kill or be killed and just one bite is all it takes to turn a human into a monster. When one of the team becomes infected with vampire venom, they are left with one burning question. How do you kill one of your own?
