No Snitches Under A Full Moon

There was a slight bite in the air when he stepped outside but Kent barely noticed it. The chill did nothing to deter him from the feeling he was experiencing. It was something he had never known before, the bittersweetness almost knocking him down. But he did not slow his gait, eager to leave the ominous building at his back far in his past. The atmosphere was different that morning, lighter and freeing despite it being the very same weather he had always known in late fall. 
Yet Kent knew there was a big difference and it wasn't just because he had been released from the Minnesota State Prison after serving six of his ten-year sentence for armed robbery. This was not a simple romp in the yard, watching his back and avoiding conflict. For the first time since he had been sentenced, Kent felt alive. 
And he was fueled by the need to exact revenge. 
His brother had been brutally murdered and using his tracking skills, he finds out that his brother's killer is already dead, the victim of a brutal werewolf attack.
As other people in the small town begin to disappear, Kent joins forces with a young college reporter to get to the bottom of things...And discovers that his brother may not be dead after all. 
He may be a werewolf...
And it is now up to Kent to stop him from killing again.
