It is a lucid account of Shri Vamadeva Shastri (Dr. David Frawley) becoming Hindu in both spiritual as well as outer traditional sense. He comes from Catholic background and couln't find answers to his questions in Christianity and hence he read about other philosophies which mainly included East and West Europeans, Egyptian, Islam, Buddhism, and Sanatana Dharma (Hinduism). He found the Yogic way to his liking and found the works of Aurobindo and Raman Maharshi very insightful.
The book narrates his experiences with different religions and interactions with people following different paths to know the supreme reality. It is a short book and clears many misconception about Hinduism prevalent in today's world such as Hindu Dharma is (and as a corollary Hindus are) demonic, intolerant, superstitious, unscientific, cruel, repressive, etc.
I would recommend that those who are unfamiliar (or misinformed) about Hindu Dharma should read this 200-page book. Shri Vamadeva Shastri was awarded Padma Shri (3rd highest civilian award of India) in 2017 by Union Government of India for his contribution to Vedic field.
