The Blue Sword by Robin McKinley is the sequel to The Hero and the Crown. The Blue Sword is a fantasy book set in the land of Damar at least 100 years after Princess Aerin. Here exists a state of cold war, until the abduction.
Harry Crew waits miserably in the grand hall for breakfast. She has just arrived in the Outlander city and now lives with the elderly Sir Charles and Lady Amelia, who insist that she do no work. She is dreadfully bored. But when King Corlath of the Damarian Hills comes for negotiations, Harry's life is about to change forever.
Although I liked this book, I preferred The Hero and the Crown more. This is because I feel that there was a lack of character depth in this book, but it is an otherwise excellent and action packed book for all ages.
