Query: Absolutely excellent

As a woman who's worked in a "man's field" for 20+ years, I really thought I knew how to play hardball. Boy was I wrong. This book by Pat Heim and Susan Golant really showed me where I was making sometimes fatal errors and how to fix them fast. The result has been more respect at work from my male peers and enough confidence to ask for -- and receive -- a substantial raise. This is a must-have book. I just wish that I had found it many years ago.
