'Terrifying and terrifyingly real, a must-read for fans of Stephen King and John Ajvide Lindqvist' - Elizabeth Hand, author of Generation Loss and Hard Light

Welcome aboard the Baltic Charisma.

Tonight, twelve hundred expectant passengers have joined the booze-cruise between Sweden and Finland. The creaking old ship travels this same route, back and forth, every day of the year.

But this trip is going to be different.

In the middle of the night the ferry is cut off from the outside world. There is nowhere to escape. There is no way to contact the mainland. And no one knows who to trust . . .

On the Baltic Sea, no one can hear you scream.
