A road trip through a near-contemporary USA (it was published in 1998) that would appeal to readers of travel books by Paul Theroux, Bill Bryson and even Michael Palin.
Like them, the author is able to map deep fissures in the national psyche - north versus south, rich versus poor, black versus white - by letting some ordinary and extraordinary people tell their story. Truth is stranger than fiction and often funnier.
Even if you don't have a particular interest in the Civil War, this book will enlighten and entertain. Good holiday reading.
