SOLVED. Sci Fi - Dystopian city in London, massive levels of concrete with the lowest social class at the bottom. [s]

I am trying to remember the name of a book I read back in 2011. It was set in an overpopulated London with large layers of concrete that buildings were built on and the lowest social class people were at the very bottom. If I remember, the govt told the people residing in these concrete towers that there was no other life or civilization when in reality the gov't officials and famous faces had their own places around the world. The main character was a teenage girl that lived at one of the lower social classes. If I'm not mistaken she had a missing twin brother or something. She would go to the arcade and and play some type of sci fi fighter jet simulator. She was the best at the game. She was basically born to fly this. If I remember correctly she was a rebel and got her hands on one of these ships and flew it out of london trying to save her brother.

I just hope I didn't dream this book up.

I also think the book may have come in a hardcover and the cover was red (Maybe it helps but don't take it worth a grain of salt)

Thanks for the help.
(excuse my grammar. I can barely keep my eyes open)
