Pelagost

Sixty thousand souls live on the back of a living leviathan—and it's about to dive. Josefin Braal, a mainland naturalist dispatched to study the creature called the Orsal, arrives in the floating city of Pelagost to find fissures splitting its streets and sulfurous gas choking its lowest quarters. Her research reveals a terrifying truth: the beast isn't dying. It's descending. Now Josefin must navigate political betrayal, a creature's alien intelligence, and the horrors nesting inside its body to save a city that refuses to believe it's already sinking.
