This is not a very fair review. The book does say it is to be used in conjuction with local maps and there is a section in the book describing the advantages and disadvantages of the various local maps. This is the case with the majority of guidebooks, which are not intended to fulfil the function of the maps. It is also untrue to say there are no maps in the book as sketch maps and an overview map are provided.
The book cannot 'lead the user by the nose' but this book does provide a lot of information on the routes which would be very difficult to obtain locally without employing a guide.
