The correct option is D Manu S Pillai
Manu S. Pillai has authored the book ” The Ivory Throne : Chronicles of the House of Travancore” , a critically acclaimed 700-page history of Kerala focused on the last woman Maharajah of Travancore. It won him the Sahitya Akademi Yuva Puraskar in 2017. Pillai’s retelling of this sprawling saga focuses on the remarkable life and work of Sethu Lakshmi Bayi, the last – and forgotten – queen of the House of Travancore. The Ivory Throne conjures up a dramatic world of political intrigues and factions, black magic and conspiracies, crafty ceremonies and splendorous temple treasures, all harnessed in a tragic contest for power and authority in the age of empire.
