Having read many 'body language' type books, this book generally followed the normal pattern, citing the usual body language 'clues' to sexual attraction, and quoting references from various research. So in that sense, it felt somewhat formulaic.
What I liked about the book, was that it was written by a woman, looking at things from a female perspective. She also enlisted the help of female friends to demonstrate in the photographs.
It is surprising how clueless we men can be, when wondering if a woman is interested in us or not. This book should serve to give confidence and re-assurance to men on the lookout for female 'conquests', and hopefully read the clues that are in front of our noses!
