Using fire and ice magic, Elli and Ansa must bring their people together to fight a common enemy in this epic conclusion to the Impostor Queen trilogy, which is a perfect fit for "fans of Victoria Aveyard's Red Queen" (School Library Journal). Now that Ansa knows she is the destined queen of Kupari, she is desperate to find a permanent home for her people, the Kriegere, in the Kupari lands. But as the small band of warriors crosses into the foreign territory, Ansa loses her fragile grip on her newly-acquired--and violent--fire and ice magic and puts everyone, including her love Thyra, in danger. Inside the walls of Kupari, Elli maintains the facade that she is the magical queen, with her secret--that she has no magic at all--on the brink of exposure every day. But as she tries to prepare the citizens to protect themselves from another invasion, unrest spreads as wielders like her beloved Oskar begin to lose control of their powers. As Kupari grows increasingly unstable, with the land literally crumbling beneath their feet, and a common enemy once again threatening everything, these two young women on a collision course with destiny must find a way to save the realm and their people from total destruction. In this epic conclusion to the Impostor Queen series, Sarah Fine's sweeping tale of two fierce leaders imbued with unimaginable power and called to unthinkable sacrifice finally answers the question: who has the strength to be the True Queen?
