The Sea of Gèvaudan is just as monstrous as the kingdom itself, filled with creatures who lurk in the deep. Helia is a princess from distant lands, bound to marry the infamously cruel prince. On her voyage across the great ocean, she makes the ultimate sacrifice and takes her own life. But as she's sinking into the peace of death, she's given a chance at a new beginning - with a mystical being named Enver, the last of his kind. A merman.
