1916. For the first time in his life, Prince Killian of Astrocia is dreading the upcoming worldwide Peace Festival. The only heir to the throne, he yearns for an escape from an arranged engagement, and he quickly finds it in the alluring gaze of the mysterious Duke Fedya.

Captivated by the Duke’s secrecy, Killian is willing to do just about anything to escape the restraints of marriage and duty – even make a deal with a fairy. With the gift of an enchanted rose, Killian is determined to forsake his destiny, even at the risk of the ultimate disgrace.

But the disgrace falls upon Duke Fedya as what was once a wish turns into a curse and the darkness can no longer be concealed. As Fedya loses himself more and more to the beast within, Killian seeks to save the man he might just grow to love.
