Redemption Ark is a great yarn, with action spaning a long time scale and many star systems. It takes quite a while to figure out that the Inhibitors have the same goals as 's Berserkers—they want to eradicate intelligent life (though there's some hint that they're doing it to stave off a more thorough cleansing by unknown agencies). Unlike the Berserkers, these killers wait quietly while monitoring commerce between the stars so that when they strike, they'll be able to wipe out all traces of the civilizations they notice. And they don't attack with space ships and robotic warriors; they build megastructures to destroy entire star systems. The humans who figure out their objectives have to make even longer range plans in order to counter them.
'sAnd the main characters here are willing and able to think that far ahead, and set up long term goals. A few of them have the longevity to pursue this kind of plan, and still interact with shorter-lived people on a human level. The factions include a borg-like collective, though they seem to follow plausible physics, and members don't participate in the group mind when they're not on the same planet. They do have faster than light travel, though there are reasons it's rarely used. They still have a civilization that spans multiple star systems, so they have the ability to hibernate while on long journeys. Given time dilation at near light and other effects, they're used to (at a societal level) dealing with people who remember the distand past at first hand, and have institutions that allow people to carry out long term plans when the principals might be away for extended periods.
One of the things that has cut down the prevalence of interstellar travel is the presence of plague, a nano-scale infection that they seem unable to stop except by physical isolation. The story starts with the return of the ship captained by a revered long-lost ancestor which seems to have been infected or attacked by a new kind of agent. After this, we follow a couple of different story lines among the borg, on a colony world in political turmoil, and following a local transport rocket pilot around a densely inhabited system. Characters and events influence one another in various ways across the different story lines.
We gradually learn that an inner cabal within the closed leadership group inside a faction of the borg knows about some super weapons created in the distant past that might be useful in fighting the Inhibitors. The Inhibitors have recently become more active, and a few factions figure out that someone needs to act. The struggle to find and control the super weapons drives much of the conflict in one story line. Other groups pursue other schemes in the converging story lines, to keep things dramatic and interesting.
Anyway, the struggles between long-lived and widely traveling post humans and ordinary people living out their lives on planets in distant solar systems are fascinating to watch, and quite plausible. The further they are from an ordinary lifespan, the more alien their motivations and goals, but most of them seem to be trying to work towards a greater good as they understand it. Even the few with truly alien viewpoints know how to work with others to achieve mutual goals.
I've read a few of
' books at this point, and I enjoy the broad scope, the immense vision, and the finely detailed characters. The stories are suspenseful, and even when they leave a hook for a follow-up story, the endings are satisfying.
