Query: Probably the best book in English

The biography, translated from French, is probably the best book available on the life of Bernadette Soubirous overall and on the events of 1858 in particular, which may have little to do with the later elaboration of the site and certainly have nothing to do with any possible commercialization of it. Those events of 1858 cannot go out of date; the real subject is contact with the eternal. This translation was published in paperback; I do not know why the paperback edition has become unavailable on Amazon.
