Switching Demons.

Luke : A broken boy who thinks he is worthless, gets high all the time, and to top it all off he's mute and there's a sharp icy blue eyed monster inside of him.

Calum : A broken boy who thinks he's unwanted , smokes half a pack a day, and to top it all off he has a brown eyed monster inside of him.

how are these two brought together you ask?
well let's say some monsters made a deal 17 years ago...
