In Everything the Light Touches we meet many travellers: Shai, a young Indian woman, lost and straying, who journeys to India's northeast and rediscovers, through her encounters with indigenous communities, ways of being that realign and renew her. Evelyn, an Edwardian science student at Cambridge, inspired by Goethe's botanical writings, who embarks on a journey seeking out the sacred forests of the Lower Himalayas. Linnaeus, botanist, taxonomist, who famously declared 'God creates; Linnaeus organizes', and his 1732 expedition to Lapland. Goethe, who travels through Italy in the 1780s, formulating his ideas for The Metamorphosis of Plants, a little-known revelatory text that called for a re-examination of our propensity to reduce plants—and the world—into immutable parts.

Drawing richly from scientific and botanical ideas, the novel plunges into a whirl of ever-expanding themes: the contrasts between modern India and its colonial past; urban life and the countryside; capitalism and centuries-old traditions of generosity and gratitude; script and 'song and stone'. At the heart of the book lies a tussle between different ways of seeing—those that fix and categorize, and those that free and unify.

Everything the Light Touches brings together, with startling and playful novelty, people and places that seem, at first, removed from each other, in time and history. Yet, all is resonance, we discover, all is connection.
