I have enjoyed much of the Honor Harrington series. Clearly, his first four books are the best, but the others have had their gripping moments. Not this book. It is a bore from end to end.
Some random thoughts:
The Honor worship has gotten utterly out of hand. How many more pages must be lavished on the central character that has had no interesting or original thoughts in 3000 pages?
There exists not a single interesting character in the Manticoran Alliance. Not a single person that I would want to talk to or meet.
Only the Peeps have anything left to say. Tom Theisman, Eloise Pritchard, and Shannon Foraker at least have some depth, some pathos, and some guts. But these character are given only a fraction of the novel to develop.
There is very little actual action, very little plot development, and the characters stagnate.
All in all, it reads like some mediocre DM in a Dungeons and Dragons game distributing the booty of the quest.
The vast majority of the book is taken up with political maneuvering. Every character that does not fundamentally agree with Weber's politics is an idiot, a coward, and is fundamentally acting in bad faith. On the other hand, everyone who agrees with Weber's politics is obviously correct, noble, brilliant, and incorruptible. (...)
Since these buffoons are in power, we essentially read 800 pages of stupid people trying to spin incompetence that would make the GOP look good.
Basically, we get to watch simpletons plot in meetings for roughy...750 pages. Very exciting.
Mr. Weber, political intrigue is like chess, only really interesting when masters go at it. Otherwise, you just get frustrated and bored.
Which is precisely what happened here.
