The Vault of Vishnu, Ashwin Sanghi

A Pallava prince travels to Cambodia to be crowned king, carrying with him secrets that will be the cause of great wars many centuries later. A Buddhist monk in ancient China treks south to India, searching for the missing pieces of a puzzle that could make his emperor all-powerful. A pre-Neolithic tribe fights to preserve their sacred knowledge, oblivious to the war drums on the Indo-China border. Meanwhile, far away in the temple town of Kanchipuram, a reclusive scientist deciphers ancient texts even as a team of secret agents shadows his every move.
