India is one of the largest contributors to the global number of out-of-school girls. Poverty, early marriage and rigid social norms keep millions away from classrooms. At the heart of these issues is the symbolic 'last girl', Antimbala, representing those farthest from opportunity and first to be denied it. What would it take to change her fate-and that of countless others? In 2007, Safeena Husain, whose own education was once interrupted, set out to find the answer. An initiative that began in a few pockets in Rajasthan has grown into Educate Girls – a grassroots movement that now spans more than 30,000 villages and has helped over two million girls return to learning. Through a network of local volunteers, it built leadership within communities, found new ways to identify out-of-school girls and track their progress, and proved that lasting change can start at the margins. Drawing on years of first-hand experience and vivid stories from her work in India's villages, Safeena Husain's Every Last Girl traces this remarkable journey – the persistence it demands, and what becomes possible when a society chooses to bring its daughters into its future.
