The Domino Effect in Books

MY CHAIN MAIL OF BOOKS

I sometimes wonder how I am reading the book in my hand. Who recommended it? The last book I just finished was The Camino by Shirley Maclaine.

We were watching Downton Abbey and I had to tell my children that the visiting American grandmother in the show (through WhatsApp)  was my favorite actress during my younger days and of course even now, Shirley Maclaine. Well, they sort of ignored my unsolicited information as they usually do. I went to Wikipedia and read about her. There I found this information about her journey in Spain on the Camino de Santiago-Camino de Santiago - Wikipedia . It also found the book mentioned-The Camino.
