About halfway through Lords of Uncreation, the third book in the Final Architecture trilogy by Adrian Tchaikovsky.
They are to space opera what his children series is to hard science fiction. It has imaginative aliens that resist monoculture stereotypes and ominous, seemingly implacable foes. The technology never descends to Star Wars' (for better or worse), but standard tropes like FTL and gravitic control are all fundamental assumptions. However, once those assumptions are made, everything that follows is consistent and reasonable to the setting.
The cast is diverse, interesting and entertaining and the pacing is nothing short of breakneck.
