Ventus by Karl Schroeder.
Possibly aka "Star Wars meets Star Trek meets LoTR, done right." The problem is it has the weaknesses of all of those as well as the strengths.
Strong points: decent characters, good action scenes, plenty of "WOW!" moments.
Weak points: the philosophical stuff felt more pretentious and technobabbly than anything else, though I'll give it points for not being as degrading and offensive as Dan Simmons. But the thing that really grated on me like crazy was the gender politics. Which is not good, because the failure of medieval social concepts is a major part of the plot!
It goes like this basically. Men are by nature
* aggressive, with a desire to fix (or reshape) the world
* unaware of other people's feelings
* fundamentally brutish and naive no matter how smart they are
* need women for emotional consolation and guidance
* more importantly, need women as an outlet for sexual energy and/or aggression
and women are by nature
* passive, with a desire to mediate and provide emotional counsel
* aware of other people's feelings to the point of overthinking everything
* fundamentally shrewd and conniving no matter how naive they are
* need men for physical and emotional protection
* need the aggression/sexual energy of men for some ill-defined reason
Not sure what to call this complex, but it should be familiar. It's common in SF and especially fantasy literature; and from what I've seen, almost always espoused by men, and almost always treated as a Truth that cannot be denied. Ventus is a pretty mild example, compared to e.g. Dune or the Kvothe Kingkiller novels.
But yeah, the rigidity of such ideas just makes me sad, in a way that even nihilism never quite manages.
I counted two female characters in the novel who defied this framework. Both were definitely lost, unhappy sorts. Also, zero characters who were not cis/hetero, and almost all European names. Which is kind of surprising given the post-mortal post-AI interstellar civilization in the picture...
tl;dr A novel purportedly about awareness is a bit too lacking in just that. Physician, heal thyself.
