The Duke's choice

Grayson is next in line for the title of Duke of Kingston. He was twenty six and didn't want to settle down anytime soon. When his father falls deathly ill, he promised his father to start looking for a wife. As he attends all the parties and balls in search of a wife. What he didn't bargain for was finding two that was marriageable. Sarah was in her fourth season, she was the first to catch his eye. Then after a couple of months during the season, Lucy started her first season. He couldn't decide whether he wanted the seasoned maiden or fresh off the farm Lucy. Who will Grayson choose? Sarah, or Lucy?
