Books to read on long flight?

At the end of July I am flying to Zurich, Switzerland from Philadelphia, plus I have a three hour layover in Philly, so I need a good book or two to read. I'm a teenager and I've read the Harry Potter series too many times to count, don't like Twilight or any of that vampire crap, I just finished the Beautiful Creatures books, but it seems like all other fantasy type books I read I don't like. I've read the Percy Jackson series and the Hunger Games series. So are there any REALISTIC FICTION books that anyone could reccomend. I don't really like girly books either.
