When Detective Sergeant Jack Sherwood found a body on the beach, he wasn’t expecting to dive into a deeper mystery. He certainly wasn’t expecting his childhood friend, Merlyn Murphy, to show up.

Now, Jack is having recurring nightmares that he can’t explain, going on adventures to find creatures he’d only read about, and learning the truth about his fear of open water. Joined by his partner, Elliot O’Donnell, the three of them discover that something dark is brewing, and they need to find the source before it’s too late.
