(W) Chris Kientz, Steve Hockensmith (A/CA) Lee Nielsen. Eric* Dominique* Ajay* and Josephine are at home getting ready for a normal school day after two successful time-travel adventures. But the day might not turn out to be so normal after all! The kids' parents remind them that today is Coronation Day* and when they get to school* they find the Pledge of Allegiance replaced with an Oath to the King. Clearly* something is amiss* and the only way to fix it is to return to the Smithsonian* this time to the National Museum of American History. Their problems don't end there: the museum's famed American Presidency exhibition has been replaced with one on America's monarchs* complete with a portrait of George Washington being crowned as the first king! Enlisting the help of Gilbert Stuart* John Trumbull* and Thomas Jefferson and using their American history smarts* our heroes must try to thwart this wicked plot to change history.
