If you have never worked on an assembly line, and I'm going to go out on a limb and bet that only a tiny few members of Goodreads have, this book will illuminate what that experience was and is like. It's also very good readable writing with excellent descriptions of characters both from the inside and the outside. And more often than not, the outside is the same as the inside, as one character tells another "They wouldn't think that about you. People can tell what you are by your face". Because the stories are linked, you can get a different perspective on some characters by seeing them through the eyes of others. It's a great way to write!
