King Sisters Lu and Min have always known their places as princesses of the empire. Lu is destined to become the first female emperor, while Min is resigned to a life in her shadow. When their father declares their male cousin heir instead, his betrayal throws both their lives into chaos. Determined to reclaim her birthright, Lu must flee the court in search of an ally. Her quest leads her to Nokhai, the last surviving wolf shapeshifter. After years in hiding, Nok is forced into an uneasy alliance with the girl whose family killed everyone he ever loved. Now they need an army to take back the throne. Left alone in the volatile court, Min’s hidden power awakens. It’s a forbidden, deadly magic that could secure Set’s reign – or allow Min to claim the throne herself. But there can only be one emperor, and the sisters’ greatest enemy could turn out to be each other.
