Detective Casey Butler has noticed fewer and fewer residents coming in to the hidden town of Rockton, and no extensions are being granted. Her boyfriend, Sheriff Eric Dalton, presumes it's the natural flux of things, but Casey's not so sure. It seems like something bigger is happening in the small town they call home.

When an injured hiker stumbles from the woods, they find themselves fighting to save the life of an innocent tourist while protecting the privacy of their town. What – or who – attacked this woman, and why?

With an unconscious victim and no leads, Casey and Eric barely know where to start investigating, and having a stranger in their midst makes the residents deeply uneasy. Everyone in Rockton wants this mystery solved – and fast.
