She can save the galaxy... If only she can save herself. For ten years, Hyperia Ariadonna has lived in exile on the winter-cursed planet of Altea, hiding from the tyrannical reign of Vespir - the ruthless Empress of the Three Worlds. Hyperia's only hope is to remain invisible by burying her past and her growing powers. But when Vespir plans to visit Altea, Hyperia knows it's only a matter of time before she's found. In her flight to escape, Hyperia uncovers a rebellion fighting to overthrow Vespir's empire-and she learns that her powers are likely the key to ending the war. But the more she recovers from her past, the more she realizes that she might be the biggest threat to her own efforts. Caught in the heart of a rebellion she never wanted, Hyperia must confront her past and her deepest fears. Will she embrace her powers to help those she's come to care for, or will they destroy everything she's fought to protect? Perfect for fans of Red Queen and Shadow and Bone, Ash and Fire is an immersive young adult romantasy combining adventure, drama, and magic.
