With the help of friends along the way, Marjorie trains to become the finest warrior Scotland has ever seen.

She also learns secrets about her father's legitimacy to the crown. Marjorie is about to find out what it means to be Scottish, and how important she is to the Scottish crown's survival. But first, she needs to survive the war, and that will take all the courage and soldiers she can get.
