Twin queens Rose and Wren brought back magic to their kingdom, Eana. But danger lurks in the shadows. Wren is troubled; her magic has become unruly. Rose is haunted; her ancestor Oonagh warns her: Surrender the throne, or face a war that will destroy Eana. As Oonagh threatens all Rose and Wren hold dear, it will take everything they have to save Eana, even a sacrifice.
