The life or a star-studded royal has not been kind to eighteen-year-old Elena Watkins. With a Council breathing down her neck and a dragon that refuses to accept her as his rider, she must convince everyone that she is ready to rule Paegeia like her parents before her. But she has made a promise to her father, King Albert, that she will not go looking for him and free the people of Etan. Elena has promised to never truly fulfill her destiny.
However, situations out of her control will soon force her to confront herself and the evil that seeks to destroy her. Elena must look inside of herself to discover if she can defeat the approaching darkness, be accepted by the people of Paegeia, bring her dragon back to light and fulfill the destiny written in their stars.
