As a middle aged man who owns and manages an independent used book store, I had to have a flip through this book when it first came across the counter. This is apparently written by a man, and a very confident man at that.
The idea behind this book is good, and there is some good advice found within. If a man is interested in you, he will find a way to be around you, either incidentally, or purposely.
The current generation of men, and in many cases, the father's who raised them, have had a significant amount of masculinity stripped from their lives when compared generations from the sixties and before. This is probably not a bad thing, but it does mean that many men today have substantially less confidence than what this book assumes.
Any advice in these pages based on the statement on page 14 "I know it sounds old school, but when men like women, they ask them out", is completely false. The book is nearly entirely based on this premise, which may be true for many men, but probably not more than half of the male population.
If, as a women, you are interested in a man, you should be able to tell if he's interested in you by way of some of the advice in this book, but if you decline to ask a man out on a date on principle, because you expect him to ask you, then the missed opportunity is on your shoulders only.
