I've finished it; a quick read. It was enjoyable, and overall a great success. There's a lot in here, enough packed into it that the novel remains interesting and engaging throughout, and yet also relatively "light" in comparison to previous books - after the big events of The Fall, it's nice to have a smaller and more intimately focused outing.
The book was very well balanced, too - for instance, the Cardassian subplot took up just enough time that it didn't feel like an intrusion. Its progress was well judged; the story was skilfully crafted. I appreciate too how the inclusion of the subplot in question plays to the station's size and scope, to the sense that life is unfolding continuously there, that myriad smaller issues are being dealt with on an ongoing basis. In a similar fashion, the Chain and the People were successful as "aliens of the week", something that we've not seen too much of recently, what with the focus on political interactions between known players. It's refreshing to have explorers come to the Federation for a change (for a big, sprawling stationary target they seem to have surprisingly few visitors from beyond...).
There were a couple of moments that made me roll my eyes a bit (if you'll excuse me saying so) - I suppose I'm simply getting a bit tired of what to me is a conservative and monolithic perspective in Trek writing that pretends to be something opposite - but on the whole this was very enjoyable and thoughtful.
I have a sometimes difficult relationship with Trek lit in general, in that - to borrow from this novel's own musings - the more I admire the glamour the more I see the rot. I had the same problem with the very high-quality Acts of Contrition, and I suppose it's a point in favour of this book's quality that I should feel something similar here. I can't say the novel actually lives up to the promise of the discussions it brings into play, but I do think it's a strong book, and it makes the most of each page.
Once again, good use is made of Garak - using him sparingly except in those rare stories that focus primarily on him (I noted the same thing, with approval, in Brinkmanship, which had only a single Garak scene). I also appreciated the various acknowledgements of the potential difficulties in accepting Elim Garak as a leader; since one of my concerns - not a complaint, just a concern - about The Crimson Shadow was the thematic discomfort that arises when Garak assumes political authority. I'm glad to see that this book wasn't shying away from that; the writing drew attention to it, often subtly, and in a very organic way stemming from the characterization, but with pleasing awareness of the complexities and possible objections. This is making me considerably more comfortable with that particular development.
Regarding the successful ongoing exploration of details relevant to the larger meta-story, I felt something similar about the novel's handling of the Alpha/Beta quadrants' political situation in general, which is in the backdrop but not the focus. Comments about being "closer to détente with the Romulans than ever", for example, which acknowledge Kamemor's efforts without bringing her into a story that's too focused and low-key for her to be involved. And it's nice to have a political dilemma that isn't high-stakes threat-of-armed-conflict but more, shall we say, realistic? The Cardassian-Romulan-Federation situation is well played. I'm also so glad to see the slow but steady thawing of relations (Romulan-Cardassian, Federation-Tzenkethi for whatever degree that's currently possible). The pax galactica of the 25th Century (as described in The Good That Men Do) is starting to seem a realistic goal.
The Tzenkethi continue to be explored well; I really enjoyed the various musings, from both Tzenkethi and non-Tzenkethi, on their social customs and the experiences of the lower grades. Reintroducing Corazame and Alden, giving them continuing character arcs, was a choice that paid off well.
Tanj's "I'm sick of all this quarrelling" was a great moment. A little funny, and also greatly sympathetic. It successfully conveyed the disappointment and regret that an expedition launched with such high hopes had been caught in such tiresome and goodwill-sapping clashes.
I did enjoy the various reflections on the social sciences, perhaps particularly because I have an essentially Pulaski-esque view on them. Having immersed in them myself, I would say they have potential value, but are far too entrenched in narrow-minded conservatism, ideology and (even by tribalist standards) an appalling lack of self-awareness and self-reflection. Give them a complete overhaul and maybe they can earn some approval.
I'll rate this one Above Average; a very enjoyable, well-written book which skilfully introduces a lot of themes and discussions into a relatively confined story and makes it elegant.
