Twelve-year-old Charlotte lives on a plantation in Richmond, Virginia, where the American Civil War is raging. All around her, citizens and the Confederate army are fighting to protect slavery -- the very thing Charlotte wishes would end. When she overhears the plantation owner conspiring against the Confederates, Charlotte knows she must join forces with her. Maybe together they can help the Union win the war and end slavery. Helping a spy is dangerous work, but Charlotte is willing to risk everything to fight for what is right -- justice for all people.
