This book covers the history of the Arabic world since pre Mohammed times to date. Of course, given the length of the book, you cannot expect a very detailed treatment nor an in depth analysis (the same author seems to offer them in other works). But as a concise and first-approach History is very useful. If you just need to get the facts, a road map and a sense of what has been the History of the Middle East, this is a very useful book. It is short, fast to read and opens up your appetite for more. It does not answer questions but it does something more important: it makes you ask lots of questions.
