A tale of forbidden love, fierce battles, and hidden treachery in ancient India.

Set in the early seventh century, The Oath blends history and fiction into a gripping story of love and war. The powerful Chalukya king, Pulikesi, invades South India, laying siege to the city of Kanchi. In response, King Narasimhavarman Pallava launches a fierce attack on Vatapi, the Chalukya capital.

Amidst burning cities, savage battles and deceitful plots, the passionate love story of Emperor Mamallan and the beautiful dancer, Sivagami, unfolds. Their love faces many dangers as dark schemes are hatched in hidden monasteries, disguised kings walk into enemy camps and assassins lurk with poisoned daggers.

From royal courts to secret hideouts, kings and monks, clever spies and skilled sculptors, saints and brave warriors fill the pages with action and excitement. As the tension builds to a nail-biting climax, one question remains: Will Mamallan and Sivagami's love survive against all odds, or will they be torn apart by war and betrayal?
