Lion is a fantastic retelling of the incredible journey of Saroo, who was completely lost from his family when he was five and how he tracked them down 25 years later. I cannot remember a thing from when I was five, but Saroo ran over his memories of his time in India again and again, so that when he was older, he was still able to remember them.
I enjoyed the book, even though I had seen the film. In contrast to other book to film adaptions I’ve seen, the film, Lion, actually kept in most of the details we read in the book.
However, if you're a fan of the film, there is still enough to justify reading — we see more of Saroo’s thought process and emotional journey, like when he decided to ride all the trains at Calcutta station, or later when he would try to find his home on Google Earth before giving up and starting over again and again.
For me, it’s just an incredible story in survival and the unstoppable power of family. It also showed me real and beautiful humans, who have no reason to help someone, but still do. The huge and positive impact human compassion can have is eye-opening.
