On the way of St. James ... in the United States

On my pilgrimage though France I stayed a few times with families. On one occasion the lady gave me a 'good night' book to read about a guy who walked the camino in Europe, but also a Pilgrims Way in the states. Starting in California to somewhere in the South (Louisiana I think). He had a credencial for that etc. I read about the part where he walked through Texas. It was really interessting. I think he is french.
I wrote the titel down but lost the paper :cry: . Now my question: has anyone ever heard of the book?

Thanks for any information
