Enjoy your book. I have the second edition. When I was going to buy the 3rd, Carter said there would be a fourth edition and to wait. Unfortunately the publisher decided to suspend all publications. I decided I would not pay the prices being asked for the 3rd edition, so I bought a PDF from the publisher for less than $25.
