I'm working on the plot outline for Book Two. As Book One was out on the frontier, Book Two is at the heart of Galactic Christendom: Holy Terra (and the solar system).
This is less of a story about fleets and naval action, and more of an intrigue-focused adventure, because we're out to thwart an assassination this time out. The mastermind villain has a loose end to tie up, lest everything get undone, so the loose end needs to die so the plot can go on. Sir Ramsey figured that out, so that loose end is in a safe location; the trick now is to figure out who's trying to kill the secured individual.
Sir Ramsey shows his pro-active practice here, starting the plot with initiating a fake leak. He sends out a rumor, varies the substance several times as he tells several people, and then waits to see which version shows up in the gossip circles. Once he determines who's prone to leaking, he sets up a trap by announcing that the secured individual will appear to testify before the Court of Stars on the recent pirate matter.
The mastermind senses that this is a trap, but cannot afford to ignore the possibility, so a duel of wits begins. Less with the fleets and the giant mecha, more with the smaller mecha, single ships, and running beam sword fights across Rome, Mars, the Moon, and other notable locations.
