Aurelia has always been warned to stay away from the Northern Shore—a place whispered to be cursed, where the sea is too still and something ancient watches from beneath the waves. But when she and her friends decide to break the rules and visit anyway, Aurelia finds herself drifting away from the group in search of quiet… and into something far more dangerous than any story ever told. Deep below the surface lives Vaelith, a thousand-year-old abyssal leviathan feared by monsters and humans alike. Cold, possessive, and endlessly alone, he has spent centuries ruling the darkest parts of the ocean without ever caring for the world above—until he notices something strange shining near the shore. A girl who looks like she belongs to the light itself. At first, Aurelia is just a curiosity to him—something rare, beautiful, and worth watching. But as their silent encounters continue across the barrier of sea and shore, curiosity turns into obsession, and obsession begins to blur into something neither of them understands. Aurelia starts feeling him in the water, a presence she cannot see but can no longer ignore. Vaelith, in turn, becomes drawn to her warmth, her light, and the way she exists so gently in a world he has always seen as harsh and insignificant. But the surface world fears monsters—and the deep sea has never been quiet for long. As human legends and ancient forces stir, the bond between a human girl of the light and an abyssal king of the deep threatens to disrupt both worlds. What begins as a chance encounter at a forbidden shore slowly turns into a connection that neither the ocean nor the land was meant to allow. Aurelia was never supposed to enter his world. Vaelith was never supposed to notice hers. And yet, the ocean has already chosen.
