For the month of December 2014, Piazza Navona and Nob Hill are on sale through my Etsy store. Originally each book sold for 10.00USD. Through December they are on sale for 7.00USD each and if you buy both it’s a total of 12.00USD plus tax and shipping. The books come gift wrapped for the holidays. Order your copy/copies now to receive the gifts before Christmas.
Just a suggestion: It’s best to read Piazza Navona first. Nob Hill is part II.
