What is the author's tone in Karma Cola: Marketing the Mystic East by Gita Mehta?

One of the most appealing and engaging aspects of the book is the way it so frequently shifts its tone. It is at times objective (e.g., when it presents and/or explores certain unarguable facts, such as how the interest in eastern spirituality virtually exploded once the Beatles expressed interest in it) and at other times subjective (e.g., when the author refers to her personal experiences with double sided exploitation). It is at times frank and blunt, at other times pointedly skeptical (and almost cynical), at still other times either anecdotal or analytical.
