Her voice could unleash a war. Twenty-three-year-old Echo del Toro doesn't know about the bride-choosing festivities the tyrannical Prince of Nyth has planned--until she's taken from her home by five armed soldiers. She's led under the cover of a magically produced storm to an opulent compound to join hundreds of girls, each vying to be chosen as the next Queen of Nyth. As she plays the charade of falling in love with the Prince, Echo realizes three terrifying truths: He is hungry for her song-magic, he has a secret plot to dethrone his father, and he is not wholly unlikeable. Faced with the strongest dark magician in centuries, Echo must know when to let her voice fly and when to hold her tongue, or she'll find herself caught in the lasting notes of a song that can't be unsung.
