The first chapter of two of this book (I listened to it in audio form, so I don't know exactly) contain a lot of profanity, mostly of the "F-bomb" variety. Because of this, I very nearly quit listening; if the rest of the book had been that riddled with swears, I wouldn't have finished it, not because I'm a prude (I'm certainly not) but because I don't feel a need to listen to someone say the "F-word" over and over and over. Thankfully, things level out after that, and the book turns into a surprisingly detailed and nuanced story about teenagers in love, mankind dependent upon and enslaved by "the Feed" (think "the Internet gone bad"), the Earth exploited to the maximum by human beings until just about everything natural has been killed (or sent into hiding... bees in the walls! Woah!) 
 Have you read about the techniques companies use to figure out what you like and want, and how to present it to you so that you will buy it? Imagine for a minute that the Internet was connected directly to your brain, 24/7. Not only does it know what you are thinking, but it can talk to you, one-on-one, and tell you about things you might want to buy and do. It knows how to shape your thinking, how to simplify you into a marketing category so it can effectively fulfill your consumer needs. This always-on "feed" also connects you to other people, so no matter where they are in the world, you can "chat" with them instantly. 
 But the Internet feed is connected so intimately with your brain functions that if something goes wrong with it, something also goes wrong with your brain. That's the situation the hero and heroine of this story find themselves in. As the world crumbles around them (environmental disaster, political upheaval, war) the two of them are experiencing their own teenage troubles... falling in love, dealing with peer pressure, and wanting to fit in while still being yourself. This book is an interesting example of a dystopian story masquerading as a utopian one; the people in the story can have most anything they want simply by thinking about it, but under the surface, their world is decaying... and they don't even know it. I might have given the book five stars, but the profanity did bother me a bit.
