Fallen Dragon, Peter F. Hamilton

So the lies and moods just kept on swinging a little further each time, picking curiously at the envelope of acceptability as if it were an interesting scab. All the while he built a defensive shell of stubborn silence around himself, which grew progressively thicker each time his father raged and his mother showed her quiet disapproval. Nothing apart from i-media interested him, nothing apart from gaining more i-media time motivated him; he had few friends, his teachers virtually gave up, and sibling rivalry at home began to resemble a full-blown war zone. With his hate-the-world attitude and his rampaging hormones, he was the basic teenager from hell.
