A hungry village boy leaves home during one of the darkest chapters in Bengal's history, promising his mother that he will return soon.He never does.Years become decades. Letters arrive, then fall silent. Borders rise where rivers once flowed. Famine gives way to Partition. War reshapes nations. Families disappear.Yet in a small village beside a river, Charubala refuses to stop waiting.Beside her stands Rakhal, a childhood friend carrying losses of his own and a promise he never spoke aloud. As the world changes around them, hope survives through memory, friendship, and the belief that some bonds can endure even the longest separation.Spanning half a century of Bengal's history, The Last Letter is a moving story of love, loss, resilience, and the extraordinary power of waiting.
