The Magic Way is a great book (as well as Juan's other books). There really isn't much overlap in the 2 books. Juan's focus is what he calls the theory of false solutions. He demonstrates a couple of different effects (ie - vanishing of a coin, oil and water, etc), and goes through the procedures of what he would do to eliminate questions that may come up such as "The coin is in your other hand" (he would show the other hand empty by using a subtlety for example).
There is a ton of great stuff in Juan's books. The problem is trying to find them. They are fetching pretty hefty prices on e-bay, but if you are able to track one down, they are well worth having.
