Eighteen-year-old Lyra Blackwater has spent her life aboard the Crimson Serpent, under the command of her father — the infamous pirate Ezekiel Blackwater, a name whispered in every port from Tortuga to Trinidad.

But when a chance encounter with a street thief named Kai unravels a trail of secrets tied to her mother’s death, Lyra is thrust into a dangerous web of betrayal, buried magic, and the shadow of a man feared by every sailor alive — Roderick Stormchaser.

As storms gather across the Caribbean, an ancient relic stirs beneath the waves — the Serpent’s Heart, a legendary artifact said to command the sea itself. It’s the prize every pirate has hunted and every empire has tried to claim. And both the Blackwaters and the Stormchasers are bound to it by blood.

To survive, Lyra must decide whether she’s her father’s daughter… or the beginning of something greater — and far more dangerous.
