My copy of corinda came through the post about a week ago, I'm about half way through and 'Wow'. Here I was spending a small fortune on ebooks for my kndle when all I really needed was the 13 steps (unfortunately not available on amazon kindle though). While the books I got are really interesting such as naked mentalism and RIP, I have to say that the stuff in the 13 steps is brilliant and most importantly (from a novices point of view it is really workable). I can see how the book, written in the 60s is still influencing mentalism today. Even the marketing for new books uses the same language as Corinda (You have a miracle on your hands etc).
I am trying stuff I never thought I would be able for, over the weekend I used an eight kings chased deck (hope I'm not giving too much away) and 'used' NLP and 'body reading' to ascertain the card. great fun and it was on extended family members. They even bought my speil about NLP, eye access cues etc even though I listed off the cards at breakneck speed

If you are new to mentalism like I am and have any kind of interest, buy this book, some of the concepts take practice and learning but there is alot that you can do straight away, so while you are learning the difficult stuff you can have fun doing the easier effects and improving your presentation skills.
P.S. CUPs combined with instant download on sites like alakazam and theory 11 is very very dangerous - you have been warned.
