This book highlights the formation of the rebel leader and his group in Saudi Arabia in the late 70s. Their extremist ideology, with so called Mahdi on their side and against the non-Islamic political views of Saudi monarchy lend them by taking over the Masjid-Al-Haram and pilgrims as hostages. Masjid-Al-Haram means Scared Mosque, so basically there shouldn't be any bloodshed, war or un-Islamic doings but during this siege it was a war zone. Blood before and blood after the siege was the outcome with the smell of dead and blood soaked carpets that didn't go away for weeks. Bullet, blackness and rocket holes on Minarets and on the building structure gave vulnerable and inexperienced Saudis a new phase.
As speaking of Juhayman al-Utaybi's name was taboo to be spoken in Saudi for months and years, this rebellion group probably the first ones who gave birth to other terrorists group in Middle-East and other nations later on. This is besides the PLO's doings in earlier years. Interestingly, this group is called rebellion/militant and not the terrorists!
