while i do agree christopher, the point i am making is that, for me personally the whole two romulan states thing was very interesting and i wanted to read more of this, now there is only one state again my...curiosity had dropped off.
same for Donatra i found her to be a interesting and indeed riveting character, and just killing her off like that was a waste of a really interesting character in trek lit.
Having a partition of Romulan civilization is interesting, I'm not sure it was viable. It may or may not have occurred on the basis of long-standing divisions as I suggested in a post last year, but that wasn't developed. That's unfortunate.
At the same time, George's novel made the point clear that this was an unstable division, that neither Tal'Aura nor Donatra wanted to make this a permanent division, and that it had the potential to escalate into an intra-Romulan war, maybe even a galactic war. We've all gotten tired of war in Trek literature, I think.
What happened to Donatra was sad, but defensible and not a deus ex machina. Having a favourite character do a mis-step after putting herself in a corner can plausibly happen.
