Two bodies.
One with an impossible wound. One with little evidence remaining.
And an apex predator just beneath the surface.

When renowned marine biologist Dr. Graham Stirling is called to Iceland after a fatal shark incident. A bluntnose sixgill is blamed for the brutal deaths of a diver and his cameraman. But the autopsy tells a different story.

One of the men wasn’t killed by a shark.

As public fear mounts and the media rushes to condemn the shark, Graham joins forces with researcher Blakely Hayes and legendary Icelandic oceanographer Gunnar Ívarsson to uncover what really happened. Their investigation leads them beneath the cold, volatile waters of Faxaflói Bay back to the exact place where the divers died.

What they find isn’t evidence.

It’s movement.

Something enormous passes through the water. Something far larger than any sixgill should be. A creature locals call the Ghost.

She didn’t kill the diver.

But she was there.

As the team descends again, the lines between predator and prey blur. Someone is hunting in protected waters. Someone knows how to kill without teeth. And the ocean is hiding the truth along with something ancient, massive, and watchful.

Because in these waters, sharks aren’t the most dangerous thing below the surface.

And the Ghost is no longer alone.
