Constabulary sergeant Corrie Welling is abducted and thrown aboard a slave ship, then washes up alone in Mocassa, a vast city on the far side of the world, after the vessel is wrecked in a storm. Unable to speak the language and saddled with a debt she has no way to pay off, Corrie falls back on a constable's instincts to protect the people she comes to know, even as an apocalyptic faith sweeps through the city around her.
