Boys of the solstice

It's the year 1830. A young brunette girl is walking to the town market to gather some supplies for the rest of winter. She meets a young boy, Alexander and his older brother Colson. The girl reveals herself to be the former Duchess Elory Rae Scotts. Elory takes in Alexander and Colson off the street, offering them a home, food and clothing. What Elory doesn't know, is that Colson is not what he seems to be.
