My 8th grade daughter read this for school, so I thought I would read it. It is based on a true story of a teacher in the late 1960's who, in teaching about the Holocaust, creates a group called the Wave. It demonstrates the idea of group-think and how the Nazis could get so many Germans to join and/or not protest their actions and policies. The experiment predictably goes awry, or really as you would expect, teaching everyone a valuable lesson. It is somewhat interesting, though terribly predictable. Also, it is around 145 pages and took about an hour to read. I am really not sure how my daughter's class spent weeks on this book (I think 6-8).
