Having spent far too much of the last few months procrastinating and not-writing, I empathise. I hope this gets easier for you as you go along. Although I haven't read Emerald House Rising, I've loved what you've posted of the characters, story and backstage of your current project.

All I can think of to get you out of your funk is that maybe you should introduce a rogue element. Perhaps if you introduced another subplot, or character (however minor), or incident into what's happened so far, you can shake it up for yourself dramatically enough that you can write it again.

Maybe (and pardon what is I'm sure an insufferable ignorance of the plot) that instead of having the chief villain explain the plan in the palace, the plan is explained (in pieces) much earlier on, and it takes a small (or even large clue) to get it all pieced together later. Perhaps you can change the role of the palace in the climaxing scenes.

I hope this has been of some help. Good luck with moving on from here. xx
