Testimonial
“I bought this book to deepen my knowledge of synergology since it was my next topic at Toastmasters International. I loved this book, I read one page after another and it so fast that I wanted more once at the end of the book. A lot of stuff for exactly “Seeing Lying”. Ideal for detectives, military, police interrogations, negotiations and even for parents of teens. ”
