Tourist guide historical romance about Ferrara

This is a guide for a trip to Ferrara and at the same time a historical romance, which is set in some areas of the city, shown in photographs. The references are also fictional, without the precision of a historical text. In my humble opinion, a simple tourist guide is not enough to get to know a city in depth, you need to be involved by associating the life of people, purposes: historical, moral, speculative and sentimental, from the Middle Ages to today.
