a series of increasingly large 'demonstrations' with support for the inside. That's to be expected in any coup, and that's all I'll say so as to prevent spoilers. Pardoe does a good job of showing how everything...snowballed.
If you really want a take on what a ACW2 might look like, go read Blaine Lee Pardoe's Blue Dawn Series. I think 3 books are out. I've read the 1st two, and they are pretty good.
