Walking to Gatlinburg by Howard Frank Mosher is the first book I have read by this author and I plan to check out his previous books. I guess it is the old adage of 'so many books, so little time.' This book is a gem. It takes place during the Civil War, but is not about the war like some of the great books by Bruce Catton, Shelby Foote and James McPherson. Also, novels by Michael Shaara such as The Killer Angels and the rest of his work as well as those written by his son Jeff give us a pretty good account of what the war was like. Walking to Gatlinburg, although taking place during the Civil War, is not primarily about the Civl War.
The book uses the Civil War as background for the story of Morgan Kinneson and his search for his older brother Pilgrim who goes missing in action at Gettysburg. Morgan sets out on an unplanned odyssey from his native Vermont to the Great Smoky Mountains. The stops he makes along the way, the adventures he experiences, the dangers he must surmount, and the people he meets are the meat and potatoes of this story. I think the review by Publishers Weekly provides one of the best summaries of this book. Here is the link: http://www.howardfrankmosher.com/books/walkingtogatlinburgPublishersWeekly.html
I hope you enjoy this book as much as I did.
