The following are the six books on the shortlist, whittled down from the 12 that made it to the longlist:

* A Chequered Brilliance: The Many Lives of V.K. Krishna Menon by Jairam Ramesh (Penguin Random House) : Based on new archival material, this a biography of a brilliant, multifaceted, complicated man, who worked relentlessly in Britain for India's freedom, who became a star in the United Nations in the 1950s; but whose public life came to a rather tragic end.

* Wild Himalaya: A Natural History of the Greatest Mountain Range on Earth by Stephen Alter (Aleph): The book weaves together the geology, geography, flora and fauna of the Himalayas, with the midst of folklore, the cultures of peoples that it sustains, through a journey across five countries, that this mountain range traverses. (The book won the Mountain Environment and Natural History Award at the Banff Mountain Film and Book Festival 2020 in Alberta, Canada, earlier this year).

* Mobilizing the Marginalized: Ethnic Parties without Ethnic Movements by Amit Ahuja (Oxford University Press): The book is based on extensive field research and shows how Dalits gain more from participating in a social movement, and dividing their political support across parities rather than voting as a block for one ethnic party.

* Midnight's Machines: A Political History of Technology in India by Arun Mohan Sukumar (Penguin Random House): The book records the historically troubled relationship of India's political class with technology, showing how the ambivalence of India's leaders on the place of technology in society, inhibited India's technological advances.

* The Unquiet River: A Biography of the Brahmaputra by Arupjyoti Saikia (Oxford University Press): This is a deeply researched study of the river, from its hydrology and ecology, to its interaction with humans and non-humans, and the way in which it has determined the course of Assam's history.

* Bottle of Lies: Ranbaxy and the Dark Side of Indian Pharma by Katherine Eban (Juggernaut): A work of investigative journalism that tells a cautionary tale.

The final award will be announced in December.
