Some vague spoilers, nothing huge, but be warned.
So it was okay. I wanted to read this book because I'm a sucker for dystopian novels, but the few clear dystopian details were really the only things I enjoyed in this book.
The setting: I like that there are tablets that people carry, particularly the green one, because I find it interesting that they would end up creating a society that can't really handle pressure naturally since they're accustomed to "handling" it by taking the calming green pill. To me, it reflects a little on the way our society handles medication for things like anxiety, and at the same time it would be interesting to analyze a society that took calming pills over even simple nerves. But the novel doesn't get that deep into the pills, not as much as I'd like it to.
The world, quite frankly, isn't all that clear to me. At some point, I thought the author was going to leave us in the dark on a lot of details, as is often the way with dystopian novels, but it's like she couldn't fully decide on a clear setting. I'm probably being nitpicky, as I often am, but I'm used to authors being very clear on what they want you to know and what they don't want you to know in order for you to fully grasp the world they've made. The author also unfortunately did not seem to know how to pace the information she *did* give us, because early on I felt overwhelmed with information that I didn't even understand.
The characters: Cassia is an annoying- sometimes infuriating- protagonist. The girl sees the wrong guy on her screen and then obsesses over him like crazy. She decides she's in love with him at a point that doesn't make sense. For a good while her obsession with him is over his ~mysterious~ background. In other words, she doesn't actually know what this kid is like (something she sort of acknowledges) but she's pretty much already chosen to throw everything away for him. The girl also jumps into a streak of rebellion pretty easily for someone who was so content with following the rules to begin with. It just wasn't convincing for me, and too much of Cassia's story was centered around obsessing over Ky so there came a point early on where I stopped caring about her. I love me some romance in any novel, but when it starts to feel like that's the only thing that matters then I get a little annoyed.
And we don't really get a well-fleshed out character for Xander either, but with the way Cassia was obsessing, and with how cheesy Ky was at times, I was starting to really hope she'd just go back to him in the end. Since that doesn't seem likely, I at least hope that someday he finds a girl that isn't as irritating as Cassia was.
The writing: This was just... bad. This was one of those books that often makes you want to say, "I don't think that word means what you think it means." It was also obvious that too often the author was trying to sound poetic, thoughtful, and deep, but instead came off as awkward and nonsensical. She often had "deep" thoughts that didn't fit well whenever she threw them in. It would be like, "I didn't tell dad about the (insert secret) and I felt wrong keeping a secret from him for the first time. But maybe we all keep secrets from each other?" or "It felt strange to be rebelling this way against rules I was previously accustomed to. But maybe we all rebel in some ways?" She kept tacking on some universal thought to her personal experiences and I couldn't help but laugh at how hard the author was trying to make her protagonist sound enlightened or thoughtful.
It isn't mind-meltingly horrible, but I'm not really interested in the sequel. I'd really rather not read any more situations in which Cassia obsesses over Ky for reasons I can't really comprehend. Try reading it if you must, but you're way better off going for The Hunger Games. Now *that* is a good dystopian novel/trilogy.
