A Curse So Dark and Lonely by Brigid Kemmerer (Paperback)

Fall in love, break the curse. Cursed by a powerful enchantress to repeat the autumn of his eighteenth year, Prince Rhen, the heir of Emberfall, thought he could be saved easily if a girl fell for him. But that was before he turned into a vicious beast hell-bent on destruction. Before he destroyed his castle, his family, and every last shred of hope. Nothing has ever been easy for Harper. With her father long gone, her mother dying, and her brother constantly underestimating her because of her cerebral palsy, Harper learned to be tough enough to survive. When she tries to save a stranger on the streets of Washington, DC, she's pulled into a magical world.
