Helena Elizabeth Charlotte Matilda Stuart (known as "Nellie" to her friends) is orphaned on the day of her birth; subsequently raised by King William III of England and Queen Alexandra, close friends of her birth parents, she grows up alongside their two sons - Edward, Prince of Wales, and James, Duke of York, as the Princess Royal. Happy, healthy, intelligent, witty, and beautiful, Nellie thrives in the royal family. Beloved by the country, she goes to law school, gains a position as a solicitor, and has many adventures. However, she does not resemble any members of her family, leading her to wonder if something is wrong with her. Then comes the announcement that her parents - after seeing both her older brothers happily married off with wives and children of her own - want her to settle down themselves! Will the dashing, brilliant, handsome, Crown Prince Sebastian of Greece turn her head?
