Publisher's Synopsis
In this next adventure, George and Gracie travel back in time to Hershey, Pennsylvania-1907. Their mission: to return an antique rug and rescue their parents. When the time machine lands them smack dab in the middle of a barn, George turns into . . . something pretty weird. And Gracie drives a car into a fence. They meet Milton Hershey, the chocolate king, who invites them to be his chocolate tasters. But when George and Gracie discover a plot to steal Mr. Hershey's perfect-and secret-chocolate recipe, they put themselves in danger to stop the thieves. Meanwhile, the evil villain, Crowe, is two steps from catching them and their time machine-and he's closing in!
