A luxury cruise. A stolen boat. A creature that wears the faces of the dead.
Ray Blake is counting down the days. In nine more, he and his best friend KC will walk away from the luxury superyacht Neptune with a handshake bonus and the deed to their dream beachside hotel. But the ship's maiden voyage - meant to showcase billionaire Sir Rufus Samuels' revolutionary AI operating system - is about to go catastrophically wrong.
When the crew pulls a mutilated, half-dead man from an impenetrable fog bank, the radio dies, the autopilot seizes control, and the Neptune steers relentlessly toward open water with no land in sight. Then the killing begins.
The head of service is gutted and dragged overboard. The captain's drunken past hides a boyhood sin. The trophy wife and her bodyguard lover are plotting murder of their own. And security chief Marnie Browning - haunted by a catastrophic failure in Tehran that cost a little girl her life - realizes the thing stalking the ship isn't a killer at all. It's something that takes the shape of your deepest guilt, offers you absolution... and then rips you open with claws. Bullets don't stop it. Locked doors don't hold it. And the castaway they rescued may be the only one who knows what it is - if he ever wakes up.
Trapped on a runaway vessel in cursed waters, a skeleton crew of misfits and liars must survive each other as much as the monster hunting them - because aboard the Neptune, everyone has secrets, everyone has sins... and the Siren is hungry.
A claustrophobic tale of supernatural horror, betrayal, and redemption on the high seas.
