In April 2009, a modest middle-aged woman from a village in Scotland was catapulted to global fame when the YouTube video of her audition for Britain's Got Talent touched the hearts of millions all over the world.

From singing karaoke in local pubs to live performance with an eighty-piece orchestra in Japan's legendary Budokan arena and a record-breaking debut album, Susan Boyle has become an international superstar.

This astonishing transformation has not always been easy for Susan, faced with all the trappings of celebrity, but in the whirlwind of attention and expectation, she has always found calm and clarity in music. Susan was born to sing.

Now, for the first time, Susan tells the story of her life and the challenges she has struggled to overcome with faith, fortitude and an unfailing sense of humour.

'When I strutted onto the stage for that audition, I was a scared wee lassie, still grieving for my mother, not caring how I looked. I think I've grown up a lot in the last year, become more of a lady, and I'm not so frightened anymore. I'm telling my story to try and show that you shouldn't judge a book by its cover, that you shouldn't just look at the label - you must look at the whole person, emotionally, physically, mentally and spiritually. I hope that it will show that dreams are not impossible, if you've got courage and a willingness to go on no matter what the circumstances.'
