I'll give you a slight bit of caution about it. Overall the book is entertaining, but with a few bumps. A lot of my friends recommended it to me, so I decided to give it a shot. (Not really any spoilers, other than about pacing.)

For me, the first third of the book was, quite unfortunately, intolerable. The main character spends half a page, every third or fourth page, constantly reminding you of how terrible their life is and how they get made fun of by the other kids for this terrible life...despite other descriptions of the world showing that he's no worse than any of the other kids really and in many respects is actually doing quite well.

The second third of the book drew me in really quickly and I was fascinated. The final third of the book was pretty awesome with the exception of a couple particularly unrealistic parts.

One thing to be warned about is that the more you find out about their worlds economy, the less sense it makes.

Other then that, the pop culture references and such are fascinating and interesting, the dialogue is for the most part entertaining, and the world building (minus the parts I've mentioned) gives you an interesting setting, particularly within the video game.

tldr: You might not enjoy the start of the book, but it is worth it to get to the end.
