Subtitled "Dispatched from the Unfinished Civil War," this book reveals the strange world of the re-enactors, unreconstructed confederates and others whose ongoing interest and involvement in the War Between the States provide an intriguing cultural portrait of the southern and mid-Atlantic states. Horowitz' trademark humor, combined with serious investigative journalism, illuminates the history of our divided nation in this account of his travels from Antietam to Gettysburg and Appomattox in the company of Robert Lee Hodge.  (USS35, $16.00)
