This second book opens where the first left off. With the Athens meeting some weird and wonderful starfish-aliens, and trading them all sorts of knickknacks for their own goods. And I'll say this for Deep Black. It's not afraid to start looking at the aliens that underpin the economy of interstellar human civilisation. We've heard a little bit about the Starfish, but this is seeing them up close, as Nbaro and the rest of the crew try to work out how to extract as much alien tech as possible for as little outlay as possible. This is, after all, a merchant voyage. But it's also a voyage that shows us a crew trying to understand the alien. Trying to see where they come from, and what it is that they want all our stuff for, and find a way to communicate. Those efforts are slow, and stumbling, but you can feel the small victories, and the potential for shattering consequences that they evoke. And the Starfish remain impressively opaque, with drives and responses that seem to sit at an odd angle to our own. They're fun to read. This is a universe populated by the strange. Speaking of which, there are rumblings of other aliens making an appearance as well (as seen in the interstitial short story collection Beyond the Fringe), and their agenda and world view is likely to change everything again.
The book manages to make all of this work by taking the high concept stuff - the galaxy-spanning humanity, the distinctly odd alien cultures, and grounding it in what feels suspiciously like 16th century Venice, but with faster-than-light travel. The Athens is a massive, brutally elegant tool, staffed by tens of thousands of people, all of whom are, after months or years in the middle of nowhere, busy politicking or screwing or feuding just trying to find a decent cup of coffee. They're our grounding influence, in their messy humanity, in their enmities and in their friendships and in their love perhaps most of all. They're good people. And, you know, also, they learn to fight hand-to hand, they fly space-fighters, and they do, sometimes, blow shit up real good. Because this is a world that fights slow, real wars in space, where getting everyone in the same place at the same time is hard, but throwing a bunch of kilometers-long railgun slugs at them once you do is reasonably easy. Deep Black has more of a focus on the xeno-culture than its predecessor, but worry not. It's still full of tense space-navy warfare, and harsh, kinetic and bloodily immediate combat, on the "ground" and in the air - all described with compulsive prose that leaves a taste of iron and gunpowder in your mouth.
Nbaro is as much of a joy to read as ever, incidentally. If you're here for competence-as-a-service, she can hook you up. There's a sense that she's grown more as a person than at the start of the first book. Here she's thrown into the deep end of trying to be a grown-up officer in what's definitely not a space navy (it absolutely is).Buried beneath watch reports and Science! and trying to fly a space-fighter and maybe also learn to be an engineer and and and. But underneath that is a vulnerability and a humanity that show us she's not just a hyper-competent plot-magnet. She's someone trying to understand what's going on, what she wants, and where her friends and her career fit in a world slowly tilting out of the known, and into something different, whether or not it's better. I've always liked her for being intelligent and brave, but seeing her run into the edges of her own personality, and need to think things through, was a delight - working on her own need to be at the front, to be seen and a hero, and yet also somehow not end up dead. And she's surrounded by some delightful supporting characters. Including the mostly-not-that-bad shipmind AI, and also her long term crush who may reciprocate her feelings, and her roommate, who has her own problems. The book wants to spend more time with some than others, but I liked the way it dealt with the issues it did have time to explore - love, loss, and dealing with the sometimes permanent consequences of a life spent at hazard. I would've liked to give them all a little more room to breathe - sometimes there's a cavalcade of names and faces and they don't get as much flavour as I'd prefer, in between the world-building and the world-exploding. But that said, the book's already big enough, and honestly I was always going to want more anyway.
The story? Well. If I can paraphrase Blackadder, it twists and turns like a...twisty turny thing. I will say that you naval warfare fans and you ground-pounders, there's plenty for you. But there's romance in here too, little sparks of joy in the dark. There's tense negotiation and catharsis and blood on the decks. There's epic space battles, and sometimes there's just training and coffee and trying to make it to the next thing before you fall over. There's being the one who shows up, the one who cares. This is high concept space opera, with a gritty feel to it, a feel of flight decks stained with oil and blood, but with some smart ideas hiding behind the explosions. This is, in short, a fine sequel, and a fine conclusion to the series.
P.S. I will say that there was some nice extra context made available in Beyond the Fringe reviewed last time, which I encourage everyone to give a read. It's not necessary but it certainnly adds some interesting facets to an already complex tale.
