The fantastic Oscar nominated movie Lion is based on this true story. It is the tale of an impoverished and malnourished Indian boy who got lost at a train station, gets on a train, and is transported to Calcutta 1000 miles from his home. He spends a harrowing month on the streets, lands in an orphanage, and is adopted by a white couple in Tasmania. Fast forward 25 years: the boy turned man exhaustively searches for his home, using google earth, and finds it. 
 If the story was not true one would say the plot was just too improbable. The author does a phenomenal job of depicting what it must have been like for that little boy before and after he got lost. I actually felt hungry when he described searching for discarded morsels of food. I also loved the drama of his internet search. The movie is better than the book (Hollywood vs a Tasmania 30-year-old) but I still read it in one sitting. Six star if that was an option.
