Angela Needham agrees to prepare the Duke of Oslington's young ward for her first Season. The duke is standoffish, completely unlike his neighbor. Justin, Lord Harrington, is congenial and very good-looking. She is caught in the middle, because the duke and Lord Harrington hate each other for a reason neither man will reveal. She should stay away from Justin, but her heart leads her to him again and again. As she tries to build a bridge over the chasm between the two men, Justin wonders if he can forgive the duke for the events of the past. If he doesn't, he loses all chances for a future with the "guardian's angel."
