This is a full performance in one routine. You basically play a 3 phase gambling routine that's tied to the story of Aunt Mary. Is it vital that you repeat the story? Pretty much, yes. But it's not that hard to learn.
Keep in mind that this is a 25 page booklet and you have a lot to learn before you perform this. You won't be doing this effect 10 minutes after you get it. That being said, it IS something you can do with any deck of cards (after you set it up) and it's something you'll be remembered for.
I, for one, would have rather seen this as a DVD simply because of what's involved, but the book is easy to follow.
