Ru is a boy from nowhere. Though he lives somewhere?the city of Calcutta?his classmates in school remind him he doesn?t look like them, and must come from somewhere else. When Ru asks his parents, they tell him he is descended from nomads. But even nomads must come from somewhere. The question, forever on the mind of the boy from nowhere, is where. Ru dreams things that wouldn?t seem out of place in the fantasy novels his father read to him when young. Fragments of a culture that doesn?t exist in this world, but might in another, where sky and sea are one, and humans sail this eternal ocean on the backs of divine beasts. He dreams of dragons, of serpents impossible. Perhaps Ru remembers dragons. Alone in a city doesn?t feel like home, Ru befriends Alice, his neighbour from the nearby Chinatown. They grow as their friendship does, and Ru finds that Calcutta may yet be a home for him. But with his best friend starting to realise that Ru?s house and family truly do hide secrets, the question haunts more strongly than ever: where is his family from? Are they truly from nowhere, migrants to this reality? And if so, what strange wings brought them across the vast reaches of impossibility to here?and what is their purpose?
