Y'all should give Kim Stanley Robinson's Mars trilogy a try. They're really long books and contain rather risque scenes, but they're still a great read overall. You like romance? They've got it. You like war? They've got it. You like politics? They've got it. You like challenging societal convention? That's one of the trilogy's selling points. You like sci-fi? Yup, they've sure got it. You like ACCURATE sci-fi? I'll put it this way, NASA sent a digital copy of Green Mars on a DVD carried aboard the Phoenix lander to Mars. Yeah, it's that accurate!
