What is the author's tone in Princess: A True Story of Life Behind the Veil in Saudi Arabia by Jean P. Sasson?

The tone of this book changes frequently, running the spectrum of emotions from optimism for change to deep grief for the injustices done toward women in Saudi Arabia. The book is meant to be a wake-up call for the modern world, to let people know what has been happening behind closed doors in this largely Muslim country. However, the woman whose story is related in this book is a woman of privilege who has many comforts that free women in the United States might envy.
