Hard to tell the true from the fiction in those type of books, but it's a very interesting subject for sure. The mass influence and how people can accept stuff just to be a part of a group, to fit in, this is scary but in the same so true, that the scary part actually...Even if it's old this book is still very actually and could be use in high school to show to teens that you have to learn to question the idea and the people around you, to make your own opinion, hopefully a brilliant one. It's a super fast read and something that will make you think so go ahead!!
