Dystopian isn't my thing, but I wanted to read a contemporary Australian author. Unfortunately this didn't do much for me.
None of the characters had terribly defining features (except for what they were good at; music, maths, communications etc., but I wouldn't count that), which made the story beige and not connect as much (or at all, really). They were severely underdeveloped and just, well, boring.
The plot had a pretty hackneyed message; watch out for technology, it'll go too far. That's partly why dystopian isn't my thing, so that isn't Blain's fault. It all gets pretty repetitive. Regardless, this particular dystopia was, again, underdeveloped and not fleshed out at all. There was little to no explanation of what certain companies were, why they were there, were they corrupt and why? Perhaps this was an intended 'style', but it didn't work in this case.
I found the narrator/protagonist incredibly boring and annoying. She, like all the other characters, had no personality and just seemed to do this. Her relationship with Chimo felt incredibly set-up and forced and overall sudden; she'd been in quite a hostile and ever-changing environment, without contact to boys, so why did she suddenly fall in love?
There were mumblings of corruption occasionally, but these led nowhere and ended up making no sense. Given that this world is so corrupt, and we have so many corrupt corporations, it would've made more sense in a dystopia like this. The characters seemed to change their minds very suddenly about which corporations they were trusting, so the reader never really knew who/what to trust and why.
A lot of the problems were a chain reaction. The overarching thing was the underdevelopment of plot and characters, which led to doubt about their choices or motivations, the environment, and the situation entirely.
Toward the end you could see what Blain was trying to touch on - that technology cannot create people, it's a nature and nurture thing - but it was so brief that I was disappointed. She clearly wanted the whole novel to be about it, but it did not come through clearly at all. Perhaps that is partly my bias toward dystopia, but I think that argument/idea is actually pretty good, and somewhat of an original idea in the whole dystopian fiction world. I would've loved to see that a key central player in the novel, and more obviously so.
