Well duuuh Xenocide was goo, well terrible. Go read Ender's Game though, loved the book. Not the ones after it, they weren't very good. I also loved the Martian and well, crap. That's all I've really read. I'm probably forgetting something, though. But look around in the sci-fi section of a library or a bookstore and read the back cover or inside flap, see what you like.
