From APFYT by Peter Turner.
Imagine doing a book test with a completely ungimmicked book, which can even be borrowed on the spot, where volunteers can select any page and any word and you will know the selected word. You need only make a small gimmick, which can be had for only pennies and is fully explained.
Peter offers deep insight and thinking into the little subtleties that take something from being an interesting effect to something that is, quite simply, stunning.
