His old belongings spilled out—along with the engagement ring he had spent months preparing for Mariya. Laughter rippled through the room.

With secrets deeper than the ocean and a past that refuses to stay buried, he’s about to show them all—Mariya, Vincent, and the entire world—that the man they underestimated is the one they should have feared all along.
