I found this book took no more than a few hours to read cover to cover. The A-Z format allows quick reference to the techniques and the stories from people who have done their own PR. You can quickly find what you remember and fancy having a go at yourself.
My dilemma with this book was that in essence it is a list of techniques and it doesn't try to piece the techniques together into a PR strategy or its linkages to your wider business strategy. However, it does do what it sets out to do and that is demystify what PR techniques can do for you and encourages you to have a go at what you fancy. After all there is no "one size fits all" with this stuff and your confidence in the application of the techniques will play some considerable part in your success. In that respect, this books a winner, it gives you the confidence to have a go at something and persist with it.
I only have two criticisms of the book - it is slightly let down by a few grammatical errors which interrupts your flow as a reader and becomes an irritation but you don't loose the sense of the book. And there are many references to the authors business, other book, and websites which becomes at worst a sales pitch, but is probably just good PR!
In summary, I liked the book, I will use it many times and I would recommend it.
