One thing I can say about Shuja Nawaz is that he doesn't pull any punches in his analysis of the relationships between the Pakistan Army, bureaucracy and politicians. His book was part of my research when I was sketching out ideas and thoughts for my debut novel, and I can honestly say that many of the things he wrote were echoed in interviews with Army personnel.
A must read for those who want to understand the "democratic" system and the relationships of politicians with the powerful Pakistan Army.
