Five-year-old Saroo and his elder brother worked as sweepers in local trains to help their struggling mother. One day, the exhausted little boy fell asleep in a train and when he awoke, he was in Calcutta, surrounded by a crowd of unknown faces. Saroo, poor and illiterate, neither knew his last name nor the name of the town he came from. In a single night he had lost his entire family and joined the countless children who had nowhere to call home in the teeming metropolis. Saroo was eventually adopted by an Australian couple and brought up in Tasmania, but he never forgot his mother. Twenty-five years later, with the help of Google Earth he found her again.A media sensation when it was reported, this will be the first time Saroo writes about his life, from his childhood in Khandwa, in Madhya Pradesh, to his days on the streets of Calcutta and his ultimate reunion with his mother. Moving and inspiring, this is an unforgettable story.
