De Jaden Troon

I'm... not entirely sure of what I just read? What was the story here exactly? There was a bunch of travelling, with a bit of intrigue happening, some assumed tension going on between Laurence and Temeraire (which then turns out to be a non-issue). There's a confrontation, and then the book is done.
This is almost like a story that could fit in an actual sequel, but it's recounted as something that happens inbetween the books or something. The story doesn't exactly warrant its own novel.
Characters are still great, but otherwise.... eh.
