Just like The New Topping Book by the same authors, which came out after this but I read first, this book very much shows its age. It is from a time when online resources like Fetlife were far more scarce than today and someone coming newly into kink would have had real difficulty finding any useful material. That is no longer the case and these books today read like someone did maybe a week’s worth of internet research to compile them.
They cover a lot of the basics quite well, but if you already have some experience, even just a little, and especially if you had even just a halfway decent mentor who introduced you to kink, they don’t offer much new insight.
I’m sure they were useful 20 years ago but I wouldn’t recommend them today.
They also have a few issues that you’d expect to see in books …
