I am a slow reader at the best of times, and that is not a good thing for such a very long and complex story. Its based around a Polish Jew who becomes a Catholic priest and post war sets up a church in Israel.
Because I put the book down for days at a time I lost track of the many varied and interesting characters and, with the usual hindsight, should have made notes of each as they appeared to remind me of who they were.
What confused me is that the book is in five long parts and each chapter may well be about characters or events many years apart from the next. In the first part alone, for example, chapters cover events or letters or whatever from 1959-83, 1960, 1985 and January 1946.
I knew I would eventually finish it and quite enjoyed it, but would only recommend it to avid readers. Not to be taken away to be read on a short holiday !
