I found this book insightful, well-organized, and highly effective as a self-teaching tool. At each of the twelve points, Ms. Walker explains the concept, illustrates examples, and provides excellent exercises to practice what she is teaching. However, I found it useful to apply the concepts to my current manuscript immediately.
Every writer will take away a different nugget of inspiration from this book, according to what concepts she strives to improve at any particular point in her career. I found the chapter on conflict particularly useful. Ms. Walker hit on precisely what I needed to hear. I dislike conflict in any form, and my manuscripts show it. With the help of the 12 POINT GUIDE, I constructed a conflict for my new work that will sustain the action throughout the story. I trust that feedback on my latest work will not include the comment 'contrived plot elements' because I have a strong enough conflict to carry the plot.
I highly recommend this guide to writing romance. There is no better advice for the cost.
