There is not much to say. We Need to talk about Kevin is depressing, horrifying, the characters are unlikeable, the story line is sickening...but it is an utter masterpiece.
This book will stay with me for a long time, I will want to forget it, to move on. I will not be able to. I applaud Shriver for having the courage to write a book like this. A small part of me has been effected forever because of this book. I don't think I will ever read it again but it will stay on my bookshelf until the day I die.
