Struggling with Onyx Storm

So I'm about 200 pages in OS and it's been kind of a slog for me so far. I really enjoyed Fourth Wing and Iron Flame as well. I'm trying to avoid spoilers but hoping things pick up soon. I may not have done myself any favors by not doing a re-read beforehand as I read IF right after it came out, so it's been over a year.

Without spoiling it, when do things start to pick up?
