Book excerpt: A charming, heartbreaking and beautifully evocative novel about fate, friendship and family Every day in the vast and vibrant city of Bombay, thousands of dabbawalla delivery-men transport hundreds of thousands of freshly prepared lunches in tiffin boxes, straight from workers' homes and into their offices. Even though the city is a maze of streets, and the tiffins carry a delivery code only dabbawallas can understand, no lunch ever gets lost. Well, almost never... When a secret note placed in a tiffin box goes astray, the consequences for a young boy are devastating. Separated from his mother and forced to work as a slave in a cafe, Kunal is sure that if he could just find his family, his life and his fortunes would change forever. Recruiting the help of a dabbawalla friend, Kunal vows to find his mother - and it seems the answer may lie with the tiffins once more. If a lost note was the beginning of his destiny, can he use another to change it?
