The film, believe it or not, came from a book written by Mickey Rapkin, which was a behind-the-scenes look at Acapella groups competing, much like the movie its self. But what I really want to know is, is it worth buying? I really want to read it, and it's on sale at BookDepository. Has anyone read it? If so, could you please comment and tell me what you think of it, and if I should buy it?
