The Last Car in the Parking Lot

I am tempted to list this book as 'unclassifiable'. Probably should. On the surface, it's about an old guy and a young guy hiking the John Muir Trail. They are searching for a missing hiker. While searching, the old guy attempts to teach the young guy about what it means to be a man. Take a chance on Last Car... I think it'll get you thinking. Brad Alan Lewis
