Author Tim Grove discusses his latest narrative nonfiction book, The World Turned Upside Down. It is the story of the dramatic Siege of Yorktown in 1781, the last major battle of the American Revolution. This real-life tale is told from five very different perspectives—that of General George Washington, the notorious traitor Benedict Arnold, the young French hero Lafayette, British General Lord Cornwallis, and an enslaved man named James who became a spy. This colorful MG/YA book includes many archival images and letters.
