Outstanding. The precursor to Regenesis (2009), one of the best books I've read, successor to Downbelow Station (1981), which provides some wider backstory of the development of this Union-Alliance series. But this is far and away superior to its precursor, if not as outstanding as its immensely involving successor. It is richly detailed, highly political and immersively psychological, and Cherryh demonstrates a higher proficiency in both spheres than any author I have read, with a confidence to her writing and a surety of her world akin to Asimov, Herbert and Banks. I'm not sure, though, if any sci-fi author comes close to her psychological and political thinking, with the possible exception of Leckie, though with far less detail there.
I have now read seven of Cherryh's various sci-fi novels - four of the Alliance/Union series, one of the Foreigner series, and one of the Rusalka trilogy, and Cyteen and Regenesis are so far beyond the quality of the others, it is still hard to reconcile that they are all by the same author. But clearly, Cherryh not only thought in minute and far-reaching detail about this 'world', but was most at home in it. And I am too.
While not quite full-blown space opera, it has, in its Alliance-Union series prequels, extra-Solar expansion, rivalling Asimov's Foundation series and Herbert's Dune series for the verisimilitude of their sociological foundations that make all great science fiction books GREAT.
It is a psychological thriller and a SF political novel - very rare. Herbert's CHOAM and Asimov's Empire are rivalled here as political meta-civilisations - something Banks has never attained directly like these - but indirectly, as vastly.
Further - perhaps most of all - I love the character and being inside of the young Ari all the way through. You not only like her, you adore her, admire her, smile at her throughout. A perfect character. A bit girly sometimes (a hint of Elizabeth Moon), for she's a girl for much of the story. But she's smart, redefines 'precocious', one of a list of uber-geniuses: Einstein, Bok... Emory. So smart, she feels sometimes 'the universe going too slow for her mind' (audiobook 5, 3, 00:47:15). And, most importantly, she is not cruel like her predecessor.
Despite the obvious technological anachronisms (taking 'tape', microfiche), this is SF of the first order. Premised on the widescale evolution of cloning, it is fundamentally about power in the new galactic quadrant. Both Emorys are constantly under threat, from without and within. Who they trust is a very limited cadre, and even those have to be suspect (it is only her bodyguard-companion clones - Catlin and Florian, beautifully drawn - who can really be trusted). Similarly for Justin and his Grant.
One major story strand is ostensibly thematically about the vicissitudes of their suffering, but the book is saved by the development of the young Ari - for although Justin may be smart, special and necessary to the new Ari, he is also an exceptionally irritating personality throughout the novel - dammit. And although Cherryh subtly alters your opinion of him as the story reaches its climax, he reminds you of having to suffer distasteful work colleagues. Yet it is this tension that pervades the book, more so than the political machinations and threats from outside, or the perverse intimate-enemy tensions from within, from Giraud and Denys. There is a distinctly vinegary flavour to this particular enforced symbiosis with Justin, and tolerance of his acid father Jordan, yet it is also these two who we follow through the sequel Regenesis, tainting everything.
It is also one of the triumphs of these books that Cherryh can lean so heavily on such unpalatable irritating principal characters and yet keep you absorbed in the story and their fates. It deals, very closely, at a personal level of feeling, with what is essentially child abuse, the abuse of power, from those who - and they exist in far too many numbers that is good for the advance of the human race - kill at the whim of a mood, any opposition of even thought, who abuse their power every day, who, even while we have an insight into their reasons, which fall under the guise of a 'bigger picture', have lost that essential need in any human, which makes them human at all: empathy. The reverberations are as profound as any deep-set. For that is a must in this overcrowded, self-destructive, remotely abusive world.
I rate these two Cyteen books so highly because, above everything - the richness of detail and character and place, as well as immersive psychology and politics - it is the person of the young Ari that fascinates and secures your affection. Living within her head, her thoughts, her feelings, her unique place, panders to your own need for being special but above all - makes you feel safe. If there is any presiding feeling while reading Cyteen or Regenesis - beyond total absorption, every reader's need of a novel - it is that wonderful cosy feeling whilst doing so of feeling completely safe. As with Cathy H. Remember her?
