In a fantasy world of wolf clans and merfolk realms, Alpha, the rightful Wolf King, shares a quiet, passionate love with Luca, a soft-spoken pureblood merman — until a political poisoning leaves Alpha comatose for three years. To keep him alive, Luca sacrifices his own merfolk blood and valuable scales to pay for the rare life-saving elixir, enduring poverty, mockery and cruelty from his greedy, status-obsessed relatives. When Alpha finally awakens, his dormant wolf spirit surges back, and he swears to protect the man who saved him. As the traitorous wolf lord Damian and the scheming noble Anna plot to seize the throne, kidnap Luca, and pass Anna off as Alpha’s childhood rescuer, the long-buried truth of a twenty-year-old sea rescue unravels — revealing Luca was the little merman who saved Alpha all along. After a daring rescue at an underground auction, Alpha claims his soulmate and crowns Luca his royal Luna at their wedding.
