I'll have to say disappointing.
Joseph O'Connor's book the NLP Workbook was one of the first ever NLP books I ever read and it was one of my favorites.
This book though is just a bunch of ideas thrown here and there, with an overpromise on the cover "Become a Master Coach." Very far from delivering that.
The usefulness of this book was a max 10 pages, plus a couple of the resources.
The weak point is that it has a lot of NLP but that is very embedded in non jargon words l, that the layman reader won't get unless they have NLP experience and if they do have NLP experience it will be very basic.
Now if the book was named, introduction to coaching, here are a few techniques some coaches use that may or may not help you, it would've probably fit better.
Rant over....
