"Do I know you?" "You've always known me, silly... I'm Tyranny, your other self. I keep you thin." One day, horrified by her reflection in the mirror, Anna makes a life-changing decision - that food is the enemy.

Her obsession with being thin and beautiful will now dominate her every waking and sleeping hour.

Should she falter or show any signs of weakness, Tyranny, her inner voice of "reason" will be only too willing to push her back into line.

Years later, when Anna finally finds the strength to defeat her personal demon, it will be a matter of life and death.
