Does anyone know of the book The Secret?

My friend bought it and she hated it. She thought it was ridiculous. One part even said basically that if you hang out with people who are ugly, you are going to be ugly, if you hang out with people who are fat, then you are going to be fat, so you should stop hanging out with people like that. She found it to be offensive in that respect, and a lot of the advice offered in it is advice you can get from any other self-help book, like be positive if you want positive things to happen. I think you should check it out from the library to see if you like it before investing money into it.
