Spellcasters A desert town and two Indian metropolises is the setting for a high-stakes game of intrigue, deception and mind-control where a journalist named Chanchal Mitra is caught in the duel of powerful forces. As the novel progresses, a mysterious woman with eyes dark as murder, a billionaire industry captain, a crutch-clutching ex-sailor, and extreme climate change events come into play. Described as a climate adventure while acknowledging its debt to works on psychedelic drugs and occult traditions, the book according to public interviews by the author engages with consumer culture, mental disorders and the secret forces battling for control of minds. Spellcasters has been described as 'part psychological-thriller and part climate fiction'. The book has been described by Amitav Ghosh as 'A phantasmagoric journey through an alternative reality of collapsed time, hallucinatory visions and spectral visitations...'

The Climate Crossroads: Literature's Encounter with a Planet on Fire A narrative non-fiction work of literary and cultural criticism examining the relationship between literature, climate change, environmental activism, and philosophical thought. Combining memoir, autoethography, literary analysis, history, and environmental humanities, the book reflects on the author's experiences as a writer of climate fiction and environmental activist while exploring how storytelling shapes public understanding of ecological crisis. Drawing connections between subjects like protest actions targeting artworks such as Vincent van Gogh's "Sunflowers", myths from the Sundarbans, Chinese weather records, and contemporary farmers' movements in India, often using the lens of fiction, the book situates climate literature within broader political and cultural debates about justice, aesthetics and planetary crisis. It studies selected climate novels through popular as well as novel theoretical frameworks including Kantian ethics, Russian formalism and the Freudian uncanny, analysing how literature provides imaginative and emotional tools for confronting the realities of planetary change and environmental catastrophe.

The Butterfly Effect At the centre of a near-future, post-apocalyptic Darkland is the chaotic city of Calcutta. Here Captain Old, a retired policeman who is also a hired assassin receives news that could help unravel the roots of a scourge that has devastated the continent.

But soon the private eye is overwhelmed by incidents that is far beyond his ken as a crime investigator.
