an obvious set-up for future Kira plot developments.
THIS!!! A HUNDRED TIMES THIS!!!!!!
I've mentioned this before, but this novel is basicly RBoE, it's a setup for more. It's like a two-parter on the tv-shows. Part 1 might not impress or make a lot of sense. But watching both episodes back to back, things become clear. I have a feeling that a lot of the things set in the 'past' will make much more sense when this story is continued/concluded.
Maybe - as I mentioned in my comments the twist at the end with who shows up on DS9 makes the Kira story a little more vital in terms of the overall storyline but that won't change the fact I didn't it find it that interesting and although not badly written it was very bland and there are many better books out there if you want to read about resistance movements and the like. With RBOE I thought the story was still interesting and well told despite what was done to Sisko so it isn't quite the same thing.
