Yes, I am foolishly working on three chapters at the same time. At the moment, I'm getting a few pages done a week. Not exactly speedy, but ongoing.
The actual chapters are subject to change, in that I might end up splitting chapters further if needed. Right now, the plan is to cover Hawaii and Japan in chapter four. Then Europe in chapter five. Then the next major event in chapter six. (The last 'major event' was Alpha's public revelation and the assassination attempt.)
