Although Sherman has had a long and rich career of government service, this book focuses primarily on her role in the negotiations with Iran which resulted in the Joint Comprehensive Plan of Action in 2015. The book is sprinkled with her accounts of growing up and the route which eventually led her to face off with the Iranians across the negotiating table. She is thoughtful and honest about the particular challenges faced by women in positions of power traditionally held by men. Certainly a great book for anyone interested in the history of these particular negotiations, but also much wisdom included for anyone considering a role in government service -- including the pain of seeing so much hard work scotched by a subsequent administration.
