It’s not on the website yet, but sources say this is confirmed–fiction-heavy this year:

Anuradha Roy: An Atlas of Impossible Longing
Chandrahas Choudhury: Arzee the Dwarf
Mimlu Sen: Baulsphere
Mridula Koshy: If It Is Sweet
Palash Krishna Mehrotra: Eunuch Park
Parismita Singh: Hotel at the End of the World
Preeta Samarasan: Evening is the Whole Day.

Omissions of interest:
Daniyal Mueenuddin’s In Other Rooms, Other Wonders, Basharat Peer’s Curfewed Night, Neel Mukherjee’s Past Continuous, Amit Varma’s My Friend Sancho. Unless they’ve all written first books that we don’t know about.
