Just finished this book last night after having it sit on my reading list for ages...
Let's start by stating the obvious. This is not Russian Science Fiction. This is an American in 2002 writing a space opera about a tsarist Russia that "once was and still can be." At least that's what the book jacket says. What we actually get is a bit of a slow burn as we're thrown right in the middle of things and introduced to some mind-bendingly fantastical technology alongside the characters and the main character's main goal. Microscopic biomechanical wonder-tech, the quasi-mystical order of cyborg "monks" that control them, some sort of power armor... It's all thrown at us all at once alongside meeting Andrei and his goal to create a new colony in the image of old Russia.
We're then introduced to an A plot (the sadistic aliens mentioned on the book jacket,) a B plot (a serial killer using the chaos caused by the aliens to hide their own gory shenanigans) that ultimately ties into the A plot, and a bunch of C plots that don't really do anything except eat up page count and confuse the reader. Is Andrei creating a second chance for a Tsarist Russia or a second Earth in anticipation of an interplanetary civil war? Don't know, his motives for the colony are vague and conflict with the explanation we are given on the book jacket.
On the positive, the story is enjoyable especially once it picks up. There are several references to Baba Yaga given an appropriate space opera update while still maintaining her mystique as one of Russia's surviving folklore figures. The characters are likable if not fully developed. Overall it is a good "popcorn" novel.
As for the negative... as other Goodreaders have noted, the plot shifts focus several times without really resolving any of the complications, the understanding of Russian and Slavic history and culture is functional but extremely basic, and there is a lot of references to the more negative side of Christian fanaticism and what feels suspiciously like Bush-era Republicans (specifically those that watch Info Wars and other conspiracy networks.) The last item is particularly hard to take seriously as most of the religious zealots and conspiracy theorists feel less like proper antagonists and more like badly-realized cartoon characters.
Overall: Not bad but after seeing that the author has an inability to stick with one main plotline, I do not think I will be looking for any more of her books...
