plain talk, riveting, and great practice
Mark's book is straight, plain talk. You instantly know he's speaking to you directly. Once I started it on the plane, I was sad that the plane was landing and I had to stop. I was riveted to try to get through it all and one plane ride. On the next plane ride I got to the practice problems, and I wanted those practice scenarios to go on forever. If he wrote another book with just scenarios, call it “marks 100 most interesting trades,” I would buy it.
