Whenever anyone asks me, which isn't often, I tell them this is it. And they invariably have never heard of it, which is a terrible shame.
I love the film, and advise those who love it as well that they SHOULD read the book too... and also read The Duchess of Bloomsbury Street, and find out what happened when Helene went to England after all those years.
And don't stop there... look up the Oxford Book of English Prose and the Oxford Book of English Verse (http://www.bartleby.com/101/), edited by the venerable Q (Sir Arthur Quiller-Couch), and see what inspired Helene to begin the correspondence in the first place (basically she decided to read everything Q mentioned, "unless it's fiction.")
