I was pleased to see Indian mythology in the form of fiction but the book disappointed me.In the book Amish claims meluha to be the Harappan civilization.He mixed several true facts about the Arian society with the Harappan culture.The lord Vishnu, Brahma and other gods mentioned in the book are believed to have been worshiped by the Aryans. I found the concept of oxygen humorous as the term was given to the gas in the 18th century by lavoisier. Many things has been given their modern names by the author spoiling the story.
However I quite like the nomenclature of the people.
