Last week, I finished reading Scott Westerfeld's "Succession" (published as "The Risen Empire" and "The Killing of Worlds" in the US). It reminded me of a past thread here that I liked very much that asked for reading suggestions for GC2 fans.
This Westerfeld work really fired up my appetite for space operas, so I'm hoping the crowd here can exert a little self discipline and just post authors and/or titles with short blurbs about why you think a GC2 fan might like the work.
I'm sure "Succession" will please several folks around here because it is full of richly detailed space battles, very "modern" SF treatment of ground battles, and a swell backdrop of sub-light interstellar conflict. The setting is much closer to the galactic core than we are, so the 80-world empire where the action happens has a volume about 30 light years across. The piece covers more than ten years thanks in part to no FTL, but it stays very fast-paced.
