By "crud," I hope your referring to A-Rod because 13 Steps To Mentalism comes through in the clutch. It's one of the better books in the game of mentalism, and is something which can only improve your mentalism performances. If you need help with your mentalism, or are new to it, 13 steps will help you hit a homerun (and will not strike out in the top of the ninth inning, with the winning run on second base, in Game 2 of the ALDS.)
Wow you see that? everyone thinks its an amazing book, I loved it. and I thought you were going to get bashed on for calling it crud haha. Yes its a good read, has a lot of good mentalism effects
