This book is a reprint of the seven booklets Lewis published in the 1990's, some of which I already have, with all the effects revised and updated. Some material is VERY interesting, altough not all is practical. However, it is one of the best books I STUDIED in recent times and my notes and comments in the index and on the tricks show that. The material is more for formal sessions or for magicians, but some of it is really outstanding. A really good book!
