Chris Cochrane never imagined abandoning school for a dangerous life in Castle Forks. He never wanted to fight immortal Demon Shadows. And he certainly didn't ask to risk his life protecting the whole world.
While on a hunting trip with his father in the wooded mountains, a magical creature invites them to an invisible castle hidden in plain sight. A castle that brings with it an impossible world, lifelong secrets, and an ancient enemy that wants to destroy humanity.
Do they have what it takes to save the world, or will the demon shadows win forever?
