I just received the book. Wow. It's not too often I actually get excited to try out a book. I own several hundred EFL textbooks, reference books, grammar books, etc. - this is definitely going to be one of the most used. Whether you need a last minute filler, an intro activity or an activity to reinforce a current topic, this book has it. All the activities are geared to promote classroom discussion and interaction. The content is divided into four sections: Conversation, Functions, Grammar, Vocabulary - covering hundreds of topics.
So far, I have told every colleague I know about the book. I still don't know why there had not been more buzz about this book. It should be on every teacher's book shelf. Cudos to the authors.
