I was looking for a quick ebook to read through my public library, and when I saw that this was immediately available, I thought, "Sure, I'll reread that." I've been meaning to reread all the old King stuff I loved when I was a teenager. 
 There was a lot I didn't remember (it's an epistolary?!) but I recognized one of the final scenes (view spoiler)[where Sue finds Carrie as she's dying (hide spoiler)] that is different than what's in the Spacek movie (the only adaptation I've seen). So, I'm pretty sure I did indeed read this back in the day. 
 I'm glad I reread it before rating it, too, because it was much better than my memory of it. Some of it is a bit dated and sections of it have a clunkiness about them that you don't see in King's later books, but I liked its leanness and its rawness. It's unflinching. Carrie's situation is dire. Her mother is terrifying. The anticipation of what was going to happen was intense, despite knowing the ending, and that's where horror novels truly succeed for me. I wanted to look away from Carrie, but I couldn't.
