As some of you on my flist know I am a big fan of the horror genre. Have been since I first picked up Pet Semetary when my aunt gave it to me around 8 or 9 years old. I've tried to get into science fiction stories/novels multiple times over the years and it never really caught fire in me like horror has done.
So...I'm putting a call out for reccs of your favorite science fiction novels. And if you'd be so kind, could you tell me why you like them. I'm not asking for a long synopsis, just what's the first thing you think of when that particular novel or story comes to mind.
eta: if you know of any online copies that would be most excellent. :D
