Dystopian novels. [i]So hot right now. [/i]

For YA (which is what you seem to be reading currently), definitely check out the [b][u]Uglies[/u][/b] series by Scott Westerfeld. It's part of a series and has to do with body/mind alteration stuff (from what I remember). Also, strong(er) female protagonist.

In a similar vein, check out [b][u]Feed[/u][/b] by MT Anderson, which is considered a dystopian classic but is more somber. More sci-fi. 

Other YA dystopian novels you should check out include [b][u]The Maze Runner[/u][/b] and [b][u]The Forest of Hands and Teeth[/u][/b] (zombies!), 

Want weird/intense/shocking? Try [b][u]Clockwork Orange[/u][/b] by Anthony Burgess if you haven't already. Written partially in a fictional slang language, 'nadsat', it's full of intensely emotional, violent scenes and has a lot of artistic/cultural references. 

Want strange/out-of-body/cool narration? Try out some of Vonnegut's novels, including [b][u]Galapagos[/u][/b], which is about the 'rebirth of humanity' of sorts after the world's economy collapses. It's told from the eternal spirit/ghost of some sci-fi writer's son. It's a lot of fun! I also recommend [b][u]Breakfast of Champions[/u][/b], which sort of breaks the fourth wall and plays with themes of free will. The characters are also hilarious. 

You mentioned space stuff. And sci-fi. And dystopias. Check out Orson Scott Card's [b][u]Ender's Game[/u][/b], which is very accessible and apparently has a sweet film adaptation.
