Venice, San Francisco, high finance, rare coins, a mystery and fun characters.  The Secret Doge by Joe Hess is the first book published by our Family (if you don't count the family cookbook, which was a massive achievement in itself).  Joe had fun writing this novel while waiting at the DMV, in doctors' offices, while watching the San Francisco Giants and generally during otherwise down time.  Think Dan Brown but replace the Vatican with the US Treasury.  Alexander Hamilton is mentioned, the former mayor of San Francisco, Willie Brown, is mentioned.  Politicians are villains. Some aspects of the book are very deep, while others are pure beach read.  Check it out on Amazon--it is an ebook --although you don't have to have a kindle to read it.  I have free kindle software on my ipad.  And if you read it and like it, please rate it on Amazon. I give it 5 stars.  But then I have a close relationship with the author!
