Let's Learn Together: Grand Mosque Seizure

I work with a wonderful Pakistani man and we both enjoy having regular spirited discussions about religion, politics, and world events. Being very ignorant about Islam, I take every opportunity to encourage him to elaborate on the subject when it comes up in conversation. Today, he began educating me on the Grand Mosque Seizure of 1979. It was quite the turning point in the history of Islam and I'm going to learn as much as I can.

Do you know anything about this event? Can you recommend any good books or anecdotes on the subject? I'll share what I learn along the way so we can all learn together.
