The book contains a good selection of routes and interesting historical information to go along with each route, it is however not a map alternative. I've tried following two of the routes so far and lost the route very quickly both times. Had I had a map I would have had a better idea of where I was at and been able to follow the route far easier.
In short - good routes, good history, but buy a map to go along with it.
