I really liked this. We have the same ornate, twisted language of the near-future world that Womack gave us in Ambient, not just in dialogue but in the story's prose too. Like it or not, Womack has really tried to come up with a new futuristic slang that's sometimes impenetrable, which is maybe as it should be in more SF. That's both the most original thing about Terraplane and its biggest stumbling block. What we don't have here is the leaden, faux-Shakespeare, clever-clever dialogue of the Ambients themselves, which was the most annoying thing about the first book to me.
As with the previous book in the series, Terraplane takes a little while to get started but gives us a pulpy, fast-paced action plot once things are established. We start in the same near-future, truly-fucked world as Ambient, but in post-collapse Russia rather than post-collapse New York. Two Dryco workers have been sent to meet with a genius scientist thought to be missing. Things go wrong, of course, but even more drastically than you might expect in a cyberpunk book. When the smoke clears, they're trapped with a wounded Russian scientist in an alternate-reality 1939 distinct from the 'past' they're familiar with. They'll have to navigate this darker, crueler alternate America if they have any hope of getting home.
Another good thing about this book is that in the people in past America actually talk normally and are nonplussed by Luther and Jake's future-lingo. That means they have to make their speech a little more clear, which benefits us, the reader. It makes up for a lot of the Russia stuff being written from, well, the perspective of an American who has known nothing but the Cold War his whole life. I think mostly well meaning, but perhaps the most dated part of the book.
I'm getting a sense that 'Dryco' is more a setting than a series, with Womack writing multiple books in the same 'universe' but rarely bringing back a main character once their book is done - as far as I can see. This was a fun read and I think I preferred it to Ambient.
