The book covers social, cultural, political, and mainly economic aspects and changes that happened during this period and its roots since the Egyptian Kingdom era. I really recommend this book if you are interested in Socio-Economic issues, or just interested to try to understand the Mubarak's era as a whole.
Ibrahim Essa on the other hand didn't miss the occasion, and published a hypothetical novel "Death of the Big Man" about a president who died in office after 30 years or ruling ;) If you like sarcasm, you will like it!
Anyway, I personally believe that one can't really judge an era unless it is over, and I don't think we are over with Mubarak's era yet. Wala heya over wana mesh wakhed Bali?
