A decade ago, Berenike, adept of the Fingertip Order, conspired to put her son on the throne at the head of a group of rebels who only wanted their futures back. She failed. Her son and husband dead, her dreams and reputation in tatters, Berenike makes the only bargain she can - she gives her magic-sealed oath to serve emperor Leontios the Unbending in exchange for the life of her young daughter, Evrim. Now, after her failure to help the rebels and her years of slavery and humiliation, Berenike is dealt yet another blow. Evrim, frustrated with her mother's dedication to a lost cause, rejects Berenike's plans. She will not fight the battles Berenike cannot. Berenike must find a way to unseat Leontios and redeem her promises to the rebels, all while navigating an almost unbreakable oath. Alone and disregarded, she will use any weapon that comes to hand - even if that weapon is her own daughter.
