It's an interesting book about Italian-American practice. The Italian traditions are more complex and the one in this book is related to the area of Neaples/Campania.
Please note that there are at least 6 different traditions so "Italian magic" is a bit meaningles unless you specifiy which one.
But it you want to learn about how tradition of a part of Italy evolved this is an interesting book.
One note: I'm Italian born and bread, had the pleasure of meeting traditional healers and I would recommend The Beneadanti by Carlo Ginzubur for real Italian tradition
Many thanks to the publisher and Netgalley for this ARC, all opinions are mine
