The authors present their central arguments for the origins and continuity of the Indic civilization very convincingly and forcefully. This is a well written, well-documented book. This book should be required reading in high schools and colleges across India. I highly recommend this to any students of ancient history. In some sections of the book, however, the authors indulge in unwarranted rose-tinted speculation, e.g. suggesting the Vedas pre-empted modern cosmological and Darwinian theories. Aside from these deviations, the book is a very objective work of historical detective work.
