I know most books are judged by the cover, unless of course the author has a huge following, then it’s not that big of an issue. The fans may feel a little disappointed in a cover choice, but grab the book to read no less, because they are a fan.
That’s a good place to be if you are a renowned author. But for some us who are striving to get there, here is my reasoning behind the covers I chose for Piazza Navona and Nob Hill.

That the fountain is a copy of Rome’s Fontana della Tartarughe in Italy (fountain of the turtles) designed by Giacomo Della Porta and Taddeo Landini in 1583. Imaging the excitement to learn that both fountains are somewhat connected surely a sign for me to consider the Fountain of the Turtles as the cover design for part II – Nob Hill.
Everything made perfect sense and the designs were selected from a hundred or more mock-ups, and that is my story and I am sticking to it. Buy the novels here
