Spirit guides

Your life changes when you start dreaming about the Tobanga, that strange totem located on Blackwell's Dormitories ground. These dreams usually end with Nathan furiously chasing you and wanting to kill you. But why? You can't help but laugh when you see Nathan at school the morning after and that's when everything takes a bad turn.
[Each chapter will have a symbolic totem animal! It's up to you trying to understand the meaning.]
