This book is well worth my recommendation. I read about it a couple of weeks ago in the Saturday Guardian newspaper and was attracted to it really because I have always been fascinated by Robert's (The Solitary Walker's) posts about his walks on the route to Santiage de Compostella. In fact I have done a couple of stretches of it in the past - more by accident than design.
I sent for the book from The guardian bookshop and it came promptly and cost less than its list price (they are an excellent place to order books)'
As well as being an interesting travel book, the kind that spots all kinds of little stories rather than look at the scenery, it is also the author's explanation of his inner journey to find himself. I found it very revealing. If you get the opportunity, do read it.
