If this book seeks to be entertaining, well, perhaps it is. If it seeks to inform, that is the main problem. It may be telling you tales that you may believe to be truths. Statements are attributed to individuals, but we do not know where the statement was copied from. Figures are given as statistical data, but we don't know where they come from. All this is rather unusual. It is normal practice to inform the reader of the source of your quotes. Not in this book. This is rather unprofessional, particularly where quotes give a negative picture of the country and its people, which is often the case. According to this book the number of Portuguese people who cannot read or write is over twice the official figure issued by the EU. I wonder whether the author got her figures from. It is worrying that this is not known. Very unprofessional. A book to be taken with great caution.
