yo my latest book is the color change, out as an e-book and a paperback. now no doubt you if you were tempted to casually check this out - it is a book devoted to a single magical effect with playing cards - you might be put off by the, um, $40 pricetag. however, the photos, by charlie heidlage, are excellent, copious, color. magic books are expensive and not available on amazon, part of the incredible hermetic mystique. it was quite the little research project and has been percolating here and there publisher to publisher revision to revision for some years.
