" First Jack and Annie don't know that Tad and Willie, two boys they've met on the White House lawn, are President Lincoln's sons. Then they don't understand that "Sam," a boy they meet in the countryside, is really a young Abraham Lincoln. However, all comes out right in the end when Lincoln gives the time traveling pair a feather they need to complete their mission, and they in turn give him a written message of hope. Children will need to read the nonfiction companion rather than this to learn facts about Lincoln, but it does provide a glimpse into Lincoln's diligent and inquisitive nature as a boy and his devotion to his family and to his country as an adult.
