On her wedding night, wolf girl Freya watches her fiancé Erik slaughter her entire pack. She jumps into the sea with nothing but the Wolf Soul Bone.
She's saved by Saelen, the Sea God's prince. He gives her the Deep-Sea Trident—and the power of the Abyss Father. She rises from a broken shield maiden to an heir of the ocean.
She returns to find Erik has stolen seven fragments of the Wolf Soul Bone. He's trying to summon the Wolf God's shadow and remake the world. Freya gathers wolf survivors, human knights, and sea folk. On the ruins of the Sanctum City, she cuts through the Wolf God's phantom with water—and ends Erik's life.
She sails west with all nine fragments—and buries a world-ending secret where no one will ever find it.
