Book excerpt: 'Do you ever wonder if you've lived the life you were meant to?' I ask her. She sighs, and dips her head. 'Even if I do, what difference will it make?' In 1988, two eight-year-old girls with almost identical names and the same love of ballet meet for the first time. They seem destined to be best friends forever and to become professional dancers. Years later, however, they have both been dealt so many cruel blows that they walk away from each other into very different futures - one enters a convent, the other becomes a minor celebrity. Will these new, 'invisible' lives be the ones they were meant to live, or will they only find that kind of salvation when they are reunited twenty years later?
