Behind the Mask
In a world where werewolves are a ruling class, Derek Hale is one of the least regarded of the alphas. If he's to hold his rank and get in a position to do some good, he can't afford to show weakness. Having human body slaves is a mark of status and so there are certain expectations of how he treats his slaves Stiles and Scott.
When Sheriff Stilinski comes to Derek to beg for his son's freedom, he glimpses a world of deception and secrets where perception is everything.
Things get even more complicated, when Derek finds himself falling for Stiles.
