The Scarlet Tide

The water changed colour ten days ago. Then the men started disappearing. In the fog-wrapped fishing village of Port Blossom, Natasha Voss has seen every kind of loss the sea can deal. But nothing has prepared her for this - ten men gone, boats found with gouged hulls and no explanation, and a darkness moving through the harbour basin at night that leaves the water disturbed and her certainty shaken.
Something is in the channel. Something vast and old and deliberate. When Natasha calls marine biologist Dr. Mara Solano in the middle of the night, the question she asks isn't what is it - it's what did we do to it. Because the marks on the hulls tell a story. The discoloured water tells a story. And the memory Natasha has carried since childhood - of an orca that surfaced wrong, that lay still with the weight of something broken - is beginning to speak in a language she finally understands.
The Language of Deep Water is a novel about grief, about the intelligence of wild things, and about what happens when the hunted become something far more terrible. It asks whether justice and vengeance can be told apart - and whether it matters, when you're standing on the dock in the dark and the water beneath you is moving. Some animals get old enough that they stop being ordinary. This one remembered everything.
