I try to review every book I read or listen to, but I have a hard time with these types of books because they are summary style. How would you rate a Wikipedia article? You may be able to, but odds are the rating would have more to do with the facticity of the article versus its writing. I have no knowledge on the topic, so I cannot review that aspect. What I can say is that this did a decent job introducing the Ottomans to a Western reader, although you would do well to get a mental picture of Eastern Europe and Western Asia as there are so many places mentioned. Your eyes will probably glaze over unless you can picture their locations in your head. The reader for this audiobook was not fantastic. I will definitely want to dig more into the Ottomans, but probably after getting a better picture of early European history.
