I too, was surprised at the rather abrupt ending. Then I thought, what the hey, it'll all get dealt with in the next book. I just hope the next one doesn't take so *&^%$#@! to come out.
I would beg to differ with The Oz on one point, though. Weber establishes a whole new direction for the series in this book, which he has hinted at before, but now seems to be developing into a major plot-line. Manticore and Haven, though, are both too busy slaughtering each other to notice it, so in that respect things are "basically unchanged". But overall, there are some big changes going on in the "Honorverse", and the situation is getting larger and more complicated than either side suspects.
