More pro-opposition books on the Syrian Civil War.

Hi. I wanna start properly reading about the Syrian Civil War. A few more pro-gov books were suggested to me (or at least from what seems to be a more pro-gov person): Asad: A Struggle for Syria, Washington's Long War on Asad and Syria, and The Dirty War on Syria. I also wanted to read books from a more pro-opposition perspective, any suggestions?

For context, I'm heavily pro-opposition (when it was around, that is).
