Virginia Creeper

Colonial Williamsburg has secrets.
During the holidays, Ellen, Tanya, and Sue want to go to the most Christmassy town in America, which Google says is Williamsburg, Virginia. While they're enjoying the magnificent light display at Busch Gardens and touring Colonial Williamsburg, Yorktown, and Jamestown, they sense someone following them. They quickly realize the creeper is not among the living.
At first, their efforts to communicate with this unknown entity provide no answers. Little do they know that he will share his message on his own terms, in his own way. The unsettling truth he shares will rock their world, but it may give them a chance to bring peace to dozens of American Revolutionary War heroes who have been lost for centuries--that is, if they can convince the creeper that they are on his side.
