Eighteen-year-old orphan Sera is the last heir of the wiped-out Silver Moon Clan. To protect her adoptive father, she assumes a false identity and enters the royal court as one of forty-seven maidservants chosen to bear the king's children. On her first night, she discovers the king cannot shift or father an heir. Using her knowledge of the ancient Silver Moon language, she bargains for her life and rises to become the king's trusted adviser. Prince Cass suspects her true identity and finds himself drawn to her. When the Queen Mother exposes her and condemns her to death, Cass returns with an army and declares her his fated mate. Her sealed Silver Moon bloodline awakens—revealing a destiny far greater than anyone imagined.
