I finished the book, I'm finding. Personally I found it very informative and builds well, sometimes a bit heavy but the subject is arid. We must recognize the good. 200 pages for the books but 60 pages of notes and good references. That's what I call a book "robust".
Roughly the book can be summarized in three parts: Christian minorities in the East, Greek knowledge in Islam and finally the Greek knowledge in Europe.
Also I totally agree with the opinion of the World criticism when he said: "Accurate, argued, this book presents the story on time is also very brave."
