The year is 1101. Your character is about to be wed to her father's political enemy in an effort to bind the nation states instead of continue the status quo of espionage, war and general ugliness. What he doesnt know is she is already in love with someone. Her brother, my character. 

The wedding goes ahead but they can't let each other go. Secrets and lies and betrayals abound.

Let me know if you're interested.
