Carrie is a girl with telekinetic powers who has been isolated from her community due to the crazy reputation of her mother. Her mother has kept her sheltered and taught her extreme religions views and opinions.
All of this made going to high school a traumatic experience for her. Especially when the torture and traumatic times seem to occur on a daily basis.
Everything comes together and she finally explodes with rage, taking it out on anyone and everyone who has ever caused her pain.
It just so happens that the whole town has bullied her, so Carrie has a vendetta against a large amount of people.
I'd give this book 5/5 for an classic original King horror book.
