I have not yet finished the book so will not put any judgement on Dr. Lynch's arguments.
The book is equal parts public sphere/int'l relations theory and Jordanian politics. Having some familiarity with both subjects greatly enhances the text and as well makes it easier to read. This is an extremely dense book, almost like a journal article the length of a book. Lynch is very good at exploring and critiquing past interpretations of Jordanian behavior, then following with his own interpretation and a powerful case to support. The book is divided into case studies which are all modern events (80's+), so do not look to this book as an exhaustive account of Jordanian history, or even modern Jordanian history since the book only focuses on select (albeit important) events to allow space for detailed analysis.
Overall, great book. Tough to read, not impossible, but definitely not for the lay. The level of difficulty is all that accounts for the four star rating.
