I think this book can be informative for those newly diagnosed with Asperger's (in the teen-adult range) and for those who want to get a more in-depth understanding of somebody close to them who has Asperger's and suffer from anxiety. If somebody is in want or need of help, with the use of CBT-training mentioned in the book, they can work it together. (Imagine learning first how to ride a bicycle, you have the standard training wheels but you also have someone by your side coaching you through the experience.)
Personally, I found that the chapters did not expand on the topics, they merely gave you an introduction. And a lot of the later chapters didn't apply to me (marriage, work/school, CBT-training and picking a psychiatrist) because I've already gone through the process or the method doesn't exist in my country.
However, I think the chapter on picking a psychiatrist is a vital reminder to anybody whether you're new or old in the game of therapy. I've had a slew of different helpers in my time and it's good to know that you don't have to settle with one that isn't helping you simply because they are a convenient choice. Sadly, I do realise that this isn't an easy option for everybody, so if you do not match, it is not your fault!
One thing I didn't much care for was how the author talked at-length about himself. Other people might like this, as it would give you a bonding experience, but I'm not a person who does.
Overall, it's a good read, good advice and gives you the knowledge that you're not alone.
