It's a tiny book, only 116 pages long, but it contains a monumental truth, another sign that one and a half million dead Armenians will not go away. It's called My Grandmother: a Memoir and it's written by Fethiye Cetin and it opens up graves. For when she was growing up in the Turkish town of Marden, Fethiye's grandmother Seher was known as a respected Muslim housewife. It wasn't true.
