Hazel Grace suspected something was a little off when her loving mummy tried to bite her when she was just six years old. Nevertheless, she lived a relatively normal life among other humans. It wasn't until she bumped into the devilishly patient werewolf, Casper Rose, that her life finally began to make sense. However, Casper proved to be gracious and seemed to have an unhealthy obsession with howling. Hazel soon learnt that Casper had taken an oath never to kiss anyone. When Hazel's loving mummy is injured in a drunk driving accident, Hazel realises her own life is at risk. Despite Casper's sharp teeth and long claws, Hazel finds herself falling for the werewolf. Only fate will decided whether he kills or protects her. One day, a vampire appears before Hazel and warns her of a darkness within Casper and that Casper has a past that involves him murdering a vampire and that he hung out with drug dealers. The vampire gives Hazel the silver arrow - the only weapon that can defeat a patient werewolf. Will Hazel find it in herself to kill the only creature who has ever made her feel truly on edge or will she give up being a vampire just to be with him?
