This cute story is historical fiction for children set in 1600s Korea. 
 The story focuses on a 12 year old girl who's father is a counselor to the king. 
 Girls and women in this class of society were not allowed outside the inner courts of their homes, except for the weddings of male relatives (female relatives were married in their family home), and on their wedding day, when they would be taken to their husband's family home, and become part of his family, never to see their own family again. Jade blossom longs to see the mountains, and life outside the walls of her family home. 
 The story teaches about life and values in 1600s Korea, and also weaves in the story of Dutch sailors who were shipwrecked on Jejudo Island, and taken as prisoners to Seoul. 
 My 12 year old daughter didn't enjoy the story, it was a little too simple for her level.
