This book was recommended to me by a very good friend and I am so glad that I read it! It has so much going for it; it is humourous, witty, insightful and desperately sad. It charts a relationship between the authors father and the girl he almost married. They had a relationship spanning 47 years, hence the title, that seemed to overcome all obstacles. There are some very funny moments in the book too, about growing up in Dublin, and some moving descriptions of less happy times in life, all in all, then a very human account of how true love is more than a feeling.
