Words sting. Songs kill. The Cruel Prince meets To Kill a Kingdom in this seductive YA fantasy debut, in which a siren must choose between protecting her family and following her heart in a prejudiced kingdom where her existence is illegal.

Saoirse Sorkova survives on secrets. As the last siren in her kingdom, she can sing any man to an early grave – but her very existence is illegal, and if her true identity were ever discovered, it would be her life on the line. By day, Saoirse disguises herself as a fae, pretending to be the perfect soldier-in-training.

By night, she satisfies her darker urges working as an assassin for dangerous mercenaries. And all the while, she keeps the biggest secret of all: that she is not always in control of her Siren powers, or her desire to kill. Then a blackmailer threatens her sister, and Saoirse’s investigation takes her to the royal palace, and her most dangerous job yet: personal bodyguard to the Crown Prince.

Saoirse expects to despise Prince Hayes. But he is kind, thoughtful, and charming, and she finds herself increasingly drawn to him . .

. until he tasks her with investigating a killer plaguing the kingdom. The problem: the killer is Saoirse.

Trapped by her deadly double life, Saoirse can’t leave the palace until she saves her sister . . .

but who will save her from herself?
