After an assassination went wrong, Ella's fate is uncertain in the Kingdom of Rairene. Meanwhile, in the kingdom of Evrotia, Raven, code name Snow White, is an elite assassin and enchanter sent to be part of the royal guard for a vicious queen who would see her executed for the power she possesses. However, being a royal guard is not as easy as Raven thought it would be when a series of attacks test her abilities while she attempts to gain the queen's trust. When Raven begins to unravel a rumor shrouded in mystery, tensions escalate in court, and her position in the royal guard becomes precarious. Raven will have to make her emotional shield stronger than her physical one as she questions the true purpose of her mission. Calla has always found comfort in the walls of Aumont, so when Lady Tremaine sends her as a backup for Raven, the cautious enchanter is more than nervous. Calla is thrust into being a maid for a prince rumored to be more beast than man. While working on aiding Raven, Calla forms an unexpected friendship with the prince. When devastating news reaches the shores of Evrotia, Raven, and Calla find themselves thrown into a war they never knew existed. Calla is challenged to push past her magical limits and Raven is confronted with a decision that will forever alter her life. The Poisoned Crown is the highly anticipated sequel to The Glass Dagger and the second book in The Kingdoms of Assassins Chronicles.
