Wren Ashcombe grew up in exile, believing her mother left her only shame. Then a kind surveyor named Tobias makes her feel chosen. When he reveals he is Prince Soren and asks her to marry him, she believes she has been rescued. She has been found. Wren is the daughter of King Corvin and Liora Maren, last of the Moon-line, whose blood can wake the empire's dormant Hollow Crown. Soren is bringing her home as a weapon against his older brother, Crown Prince Kaelen, and has been dosing her tea to keep her wolf quiet. At court, the mate bond snaps into place with the wrong brother: the feared Ice Prince, who is already hunting a poisoner. As the conspiracy closes in, Wren and Kaelen become allies, then lovers. In the end, Wren must decide whether anyone else gets to say what she is worth, or whether she will claim her name, her crown and the man she chooses.
