Princess Lily of Lawrence is bound by a dragon-blood pact to marry Dragon King Arthur. Rather than submit, she tries to take her own life. To save their kingdom, her brother Prince Laren takes her place as the substitute bride.
Arthur has loved Laren since the boy saved him twelve years ago. Even knowing Laren is male, he completes the marriage and uses pure-blood dragon magic to reshape Laren’s body. Dragon eggs can only be conceived by two souls in true love—but the old Dragon King and noble Cecilia oppose them and plot to kill Laren.
Tormented by Arthur’s possessive love and deadly threats, Laren wavers. He conceives a dragon egg during a fatal duel with Cecilia, and its power saves his life. Believing he is only a breeder, Laren clashes with Arthur, who swears his love belongs only to him.
Laren falls into a trap in Lawrence, where Prince Karl humiliates him and tries to seize Lily. Arthur arrives in black-dragon form to save him. Laren deposes his foolish father and places Lily on the throne. Returning to Dragon Castle, Laren gives birth to a dragon heir. When the old king launches a coup, Arthur crushes the rebellion and seizes the crown. He holds a grand coronation and names Laren his Dragon Queen. The pair live in peace with their child.
