Julia Ainsworth, a young princess of the kingdom Castles, is about to turn seventeen, the year when she thinks her only worries will be her mother finding a husband for her. Instead, she is faced with deciding between her childhood friend, the handsome Prince Edward of Hill, and the dashing William Adams, who is part of an important dragon hunting family. While sorting out her feelings, she must also confront a war, the rule of a kingdom, the death of a friend, and the possibility of marrying someone entirely different than the boy she’s in love with.
