I have to say this for the trick: the description is true...for the most part. There are no prearranged stooges or confederates, but if you pick the wrong person to do this with you, you're in trouble. You're actually setting up for an instant stooge, which is enough to steer most folks away. This is an effect that will amaze everyone else, but not the person you are doing it with, and that's what I don't like. While I'm the first to admit there's a time and place for this sort of thing, the Hoy Book Test is a much better choice and it allows the books to be examined at the end. Understand that this is a parlor or stage effect, and not an intimate piece of mind reading for one person.
There is a separate routine to be used with the "San Francisco Travel Guide" book by itself, but it's equally unimpressive. You can still allow the volunteer/stooge to choose any word from the page and it's what was written beforehand in a sealed envelope onstage. It doesn't change the fact that this is a lame effect.
For the price, this is far too expensive. If this was $25, I could see it being a great first book test for a beginner or comedy magician. But if you're going to spend this much money on a book test, go with the Dracula or War of the Worlds book tests.
