Betrayed by My Childhood Friend, Married to the Tyrant of Atlan

In the underwater kingdom of Atlantis, Vena—an illegitimate daughter—is cast aside and offered as a tribute to the tyrant Kieran. But Kieran is the boy she saved years ago, and he's returned to repay that debt. He awakens her sealed power, and they forge a soul bond. Trained by him, Vena becomes a general. Leading an army home, she exposes a conspiracy, reclaims her mother's stolen legacy, and stands with Kieran to face an ancient evil rising from the abyssal rift.
