Two miles down, the ocean doesn't care about survival odds. Lyra Bennett knows this, and she goes anyway.

When her submersible fails in the crushing dark of the deepest trench, death is the logical outcome. What she gets instead is Nerissa, pulling her from the wreckage and breathing life back into her with a kiss that shouldn't be physically possible.

Nerissa is no ordinary rescuer. She's a creature of the abyss, beautiful and lethal in equal measure, bound by ancient laws with one clear directive: humans who discover her kind don't get to leave. The pull she feels toward Lyra the moment their eyes meet is inconvenient at best, catastrophic at worst.

Lyra keeps diving deeper into oceanic secrets she's only beginning to understand. Nerissa keeps finding reasons to stay close, burning through the rules that were supposed to make this simple. Glowing marks bloom across Lyra's skin. Truths surface from the dark water between them. And the hunter who spent centuries protecting the deep now faces the one choice her laws never accounted for: her ruthless kin, or the only woman who has ever made her feel something worth protecting.

Love in the abyss doesn't follow pressure ratings or natural law. It just pulls.

How far will a siren go to keep her human, and how much is Lyra willing to surrender to the dark?
