The Peasant King

When her mother, the Persian king's famous senior scribe, is kidnapped, Jemmah and her sister must sneak undetected into enemy territory to rescue her. As they flee through dangerous mountain passes, their survival depends on the skills of a stranger they free from prison: a mysterious prince named Asher. Asher has only one goal: to destroy his father, the king. Jemmah must convince Asher to give up everything he has worked for, all for the sake of a higher purpose he's not sure he believes in.
