"His writing career spanned over 50 years during which he worked on more than 270 books. Close to 25 million copies of his books were sold worldwide, and were translated into over 20 languages." Source.
Over the years, I have thinned out my books, so I went from owning about five of dePaolo's books to owning just one: the first Strega Nona book, published in 1975. He went on to write ten more books that feature this wise, ageful, Italian grandmother.
