It was indeed a moment-of-a-lifetime for Olympic medal-winning boxer M.C. Mary Kom from Manipur when megastar Amitabh Bachchan unveiled her autobiography on Monday.

For Kom, who has made significant contributions in breaking stereotypes about women, this book is an attempt to cover the inspiring life of the 30-year-old and how she broke all shackles of custom and society to reach where she is today.

"Mary Kom is already a legendary figure in the country, loved and admired by all. She has made innumerable contributions in breaking stereotypes about women, more so from the northeast. The book beautifully brings out her indestructible spirit and is an inspirational read for everyone," Amitabh said after unveiling her autobiography "Unbreakable".

Speaking on the occasion, Mary said: "My struggle has been one that many in our country face, especially women. The reason I decided to pen my story down was so others could read it and feel that if I could achieve what I have, so can they."
