From a Tesco check-out to the X Factor stage ... Mary Byrne has lived every undiscovered singer's dream.

With a voice of pure gold, Mary Byrne took X Factor by storm. Millions tuned in each week to propel this incredible, brave and hugely-talented singer to a life of stardom.

And as the lights went down on X Factor Mary Byrne's dream just kept getting better: she recorded a number one hit album; sang for the Queen of England; performed with American legend Neil Diamond in front of a 40,000 audience; and joined the cast of Grease the Musical as `Teen Angel'.

In This Is My Life, Mary relives every moment of her twelve amazing months and takes the reader behind the scenes of X Factor to meet the judges and contestants and witness the real ups-and-downs of the boot camps and the live shows. Delving into her past, she recounts, in her frank and honest fashion, stories of colourful relationships, broken hearts, life on a kibbutz, world travels and heart-stopping moments.

The inspiring, funny, heart-warming and hugely-entertaining story of a woman who found fame against the odds.
