Query: A great book for firefighters and families

As the wife of a firefighter I read this book with love and affection, as it helped me understand how to help my husband and his stress dangers. I can now deal with his stress (and mine) in an informed way, which is more effective than blindly trying home remedies. This will help families use stress reducers in dealing with the special people in their lives. I think this is the most useful book you can buy in the area of firefighting. Even more than promotional study aids for promotion.
