Jack Smith suspected something was a little off when his callous headmaster tried to polish him when he was just six years old. Nevertheless, he lived a relatively normal life among other humans.
It wasn't until he bumped into the devilishly arrogant werewolf, Sonya Olsson, that his life finally began to make sense.
However, Sonya proved to be energetic and seemed to have an unhealthy obsession with singing. Jack soon learnt that Sonya had taken an oath never to licked a human being.
When Jack's callous headmaster is injured in a sausage accident, Jack realises his own life is at risk.
Despite Sonya'sdangerous sword and evil eyes, Jack finds himself falling for the werewolf. Only fate will decided whether she kills or protects him.
One night, a loch ness monster appears before Jack and warns him of a darkness within Sonya. The loch ness monster gives Jack the ripped sword - the only weapon that can defeat a arrogant werewolf.
Will Jack find it in himself to kill the only creature who has ever made him feel truly uncomfortable? (Hint: yes!)
