A king’s secret daughter is swept into romance and danger in this tale of royal intrigue. The ruler of Icarus is cunning and ruthless, yet Iliana Kracos has seen another side of Demetrius De Sante. And after an explosive night of passion together, she agrees to marry him. Yet when he reveals her true parentage—she’s heir to the throne—it puts her bridegroom in a new light. Iliana isn’t sure how she can trust Demetrius. Does he truly love her, or is she merely a pawn in his royal game? But Demetrius assures he’ll protect Iliana at all costs, and with a ruthless assassin targeting royal heirs, Iliana has no choice but to put her faith in the man she knows the least—her husband.
