Just finished it the other day. Some random thoughts:
-Kind of surprised Bacco dies in this book after it seems like she just survived the events of another assassination (although I think it's been like 2 years later now or something).
-The Kira in the Bajoran past segments were pondering, I had to skip through them pretty fast. I think less time should have been spent here and more time with the reformed DS9 crew dealing with the new station/aftermath of the assassination.
-I guess we're heading toward some new thing where Sisko's daughter is some kind of new Emissary or hybrid between corporeal beings and the Prophets?
