This book is titled “Sandy” or “Sandie” I believe.   It’s a story (real-life) written by a doctor about the death from his wife, Sandy (born as Alexandra) from cancer.  I think she must have died in about 1967 or 1968.  She had a 3 year old son called Alexander.     I read the book sometime between 1978-1982 when I was younger.   I’ve always wondered if I could find a copy of it and all my research has come up with nothing.   It’s possible I have some of the details wrong.  I got the book out of the Rochester, NY Public Library at the time.  It was in hard-cover.  I am sure that it was published by a “reputable” publisher.   I have searched for “cancer narratives” to no avail.
