Query: I gave this to my grandmother and she loved it

My grandmother, a former teacher, is in her nineties and spends her days reading. I always give her books, usually history books, because of her fondness for teh subject. She has often told me about the experience of living through the twentieth century with its technological changes. I sent her this book and she loved it. She said that one of my uncles already has dibs on it when she is finished.
