Grace's brother and family are part of the Wide-Awake movement, working to elect Abraham Lincoln. But Grace has to stay at home to help with chores, and never gets to be a part of the plans. She longs to make a difference but she can't figure out how, until she comes up with a very original way to make Mr. Lincoln more popular. She writes a letter to the soon-to-be president, telling him that he would be much more popular if he would only grow whiskers.
This unusual letter inevitably leads to a change in Mr. Lincoln's appearance, and to the touching historic encounter between this bold little girl and the President.
