As of now the most recent book in the Kirov series, Firedrake combines the worst and best of it all. The worst is that all of the structural problems are still there and that the wargame lets play structure is beginning to wear thin, especially with the foreshadowing that this particular timeline is getting erased/destroyed. The best is, well….
The best is that plot points involve the ship transported to a bleak, dark, empty world where only hostile mechanized drones roam the seas and skies (was it Skynet or Yawgmoth that was responsible? :p ). Then it moves into another timeline courtesy of supervillain Ivan Volkov, where a Third World War (the fourth in the series) is about to begin, one where Japan won the second thanks to Volkov giving them nuclear bombs.
The Kirov series is best when it wargames out drastically changed situations, and that is the case in half of Firedrake. The other half is wargame action as usual.
