An exciting historical adventure, co-written by the New York Times bestselling author of the Origami Yoda series!

Stonewall Hinkleman (yup, that’s his real name) hates participating in historical reenactments with his Civil War-obsessed parents. Who wants to pretend to fight in some old war anyway? But one day, Stonewall finds himself transported back in time to the actual Battle of Bull Run-and he’s not alone! Mr. Dupree, an ardent Confederate from Stonewall’s time, has also traveled back in order to change the outcome of the whole Civil War. Stonewall needs to use all of his knowledge of the battle to stop Dupree and save the course of American history as we know it.
