Query: Different book, same story

I own almost all of Kotter's books, and for the most part agree with his business philosophy. I was required to purchase this book for a class, and was pretty disappointed to find out that it is almost identical to "A sense of urgency" and "The heart of change". If you already own these books, save yourself the money and don't purchase "Leading Change".
