The title promises a broader and more rounded view of Sicily than what we actually get. Instead of a balanced overview of many aspects of the history of the island, we get an awful lot of Cosa Notra, with the occasional short chapter, or even just a few paragraphs, on a particular typical recipe or representative work of art, and then it's back to the mafia stuff again. Which is fine, if that's what you're interested in. Personally I found myself skimming over some of the interminable and hopelessly convoluted descriptions of the internal power struggles, in order to get to the political angle involving Andreotti, or the personal stories like that of Marta Marzotto.
Robb is obviously intelligent and knowledgeable, although he leans a little too heavily on one particular source: the legal dossier titled The True History of Italy, and I sometimes felt that he got bogged down in trying to present too much information rather than communicating some key facts more clearly. Then again, when it comes to Sicily it seems that very little is clear or uncomplicated.
