The back cover called this a cross between Brave New World and 1984, but I would say it's more of a cross between Brave New World and The Giver. All of which is to say, it falls into that category of dystopia where authors extrapolate their biggest socio-political fears to a hyperbolic degree and create unlikely extremist societies. I tend more towards the "breakdown of society" dystopian novels like The Road or The Earth Abides. But, lo and behold, I actually liked this one.
I think part of my enjoyment from this book came from the believable main character. She was flawed, capable, and quietly questioning in a dogmatic society. She didn't rail against the system internally or externally, but she certainly had some independent thought that made her question aspects of her life. Some of the ancillary characters were well done as well, serving as more than just cut-outs for a philosophical sounding board. And while the societal juxtaposition of the two main civilizations was a bit overdone, the world building here actually worked.
My biggest issue was that the ending was rushed, note I didn't say bad, just a little too epiloguish. And there were a few minor holes in the ending as well, but nothing I couldn't get past. I think a sequel could have been easily written or even just extend the ending 50 pages, but I also appreciate that the author had a story to tell and did it, without going for the money grab of the ubiquitous trilogy. This was a solid four stars all the way through and probably makes it into the top 5 dystopian novels of all time for me. Pick it up off the shelf if you see it and see what you think.
