The book is a bit out-dated in the sense that it doesn't incorporate any use of IT as we do today (it still mentions chalk on the blackboard!), however overall the activities are very clearly outlined, and great for getting students actively learning together.
Recently I tried the "Guess Who: Mystery Classmate" activity with my year 7s (who are on the whole truly enthusiastic students). We have been doing description and body parts this term, and I must say, it was an excellent consolidation activity.
