The problem with this novel is not the setting or the beginning: it's a sci-fi distopia, with an alien-occupied world where aliens are vastly superior to humans, and these eke out a living trading and peddling stuff, including identities (which, apparently, are inserted in the blood as if the blood itself didn't have something called DNA which is identitary enough). There are little fights, new and weird characters come in (robots! humanoids! Friendly and obnoxious aliens!) and you have your quest laid out for you: you have to save the world, but, barring that, you have to save yourself... and there's this place called Harmony (the alternative title of this novel) where people live, well, in Harmony and aliens leave them alone. And then what? Well, it turns out (spoiler alert) not that much.
This novel has nice ingredients. The alien language starts a bit annoying, but eventually you get used to it, but it turns out to have a very tangential effect on the plot, and even this seems to be included just for the record. Aliens are imaginative and have original features, but this does not seem to have much influence on the outcome either. Motivations, origins, and, eventually, showdowns are not there or are in a different place where they should be. There's, for instance, this love story between Dodge and Hope, but it just doesn't click. Maybe because the characters do not click either: Dodge and Hope seem absolutely lost and anhedonic, they just don't care what happens to them either way, even if their friends and family fall around them.
All in all, a disappointment. Not a complete disappointment, that's why I give it two stars. Also because there were no two-stars reviews.
