Actor Emraan Hashmi will soon launch his book - 'The Kiss of Life: How A Superhero and My Son Defeated Cancer' - in Mumbai on March 20. The book written by Imran tells the struggle around his son Ayan's cancer treatment. The cover page will be chosen by fans in a vote online. Sharing a video on Facebook, the actor said, “I am happy to announce that there is a special event on March 20 in Delhi. It's for the launch of cover of the book. But before that... I am a bit confused. We have some really good images that we have shortlisted... Some six to seven images shot by Rohan Shrestha. They are really nice candid images of me and Ayan, and we don't know which one we should carry, so, I'll leave it to you all.” The book is co-authored by Bilal Siddiqi, and will be published by Penguin Books India, in English, Hindi, and Marathi.
