Again, not got Plagues of Night yet (it's on order though), but I've read Rough Beasts and that says that Kira resigned from Starfleet and joined the church. The specific circumstances were not revealed at the time. And I don't remember any exposition regarding Odo and/or the Dominion at all, but based on some people's assumptions about the cover of the next book Raise the Dawn, some news may be coming on that point.
Saw the cover for Raise the Dawn
. No more DS9 station?
Anyway, so Kira becomes a monk or does she spend the rest of her days in a monastery?
