Well I dunno if you don't mind a bit of romance, and a lot of great plot, cyborgs, diseases, crazy things happening, I suggest "Cinder" by Marissa Meyer. It's the first book in the series of the "Lunar Chronicles".
I've read all four in the series, in like two days. The fifth book is coming out this year. . .=/
Anyway, it's a great series if you like science fiction. It's like almost a spin-off of Cinderella except a whole lot more epic.
