Teen/Young Adult Books about the future?

I, Robot by Isaac Asimov? Freaking awesome. Just look in the sci-fi section!

I really need a book, I like stuff about the future. I've read:
Uglies Series
The Host
Twilight
A bunch of other stuff, but series suggestions are appreciated.
I don't really like other books about Vampires.

Skin Hunger- it is two stories, one the future, one the past. Really good.
