ShapeShifters

Max had lived a normal life, oblivious to the fact that humanoid monsters which named themselves 'Shapeshifters' existed all around the world hidden within society. As he grew up Max followed a path in life normal to humans but in doing so he accidentally became one of the shapeshifters, this turn of events revealing to him a different side of the world he thought he knew. (For people that might've stumbled upon the novel as of now I am rewriting it)
