Mistral Marsh has always been dangerous. Smugglers know its hidden channels. Travelers stick to the main roads. And everyone knows to be home before dark. But something has changed. Three caravans have vanished — merchants, guards, families — swallowed by the fog without a trace. The marsh itself seems to beholding its breath. When Kira Duskwalker and her companions ride east to investigate, they find a land gripped by a new kind of fear. Creatures in the water. Ambushes that feel coordinated. And a lone smuggler barricaded in her waystation, counting crossbow bolts and waiting for a rescue that never came. Whatever is happening in Mistral Marsh, it's not bandits. It's not beasts. And it's getting worse.
