Query: Excellent Book!

This is an excellent book. I highly recommend it. It is great for people who are new to the MCS/Chemical Sensitivity world. It also takes you allot further. There are so many things in this book that others do not cover. There is also a nice resource listing of where to buy special products just for the Chemically Sensitive individual, I found that very useful as well. I would say if your new to MCS then this is the book for you. It is the most comprehensive, straight forward easy to read version. I would start here and then move on to others by Bonnye L. Matthews Or William Rea.
