It's been nineteen years since ten-year-old Laurel was given a life sentence and six-year-old Rosie was given a new identity.

The sisters were the very picture of innocence: two little girls who loved to listen to their mother's bedtime stories and play make-believe in the garden. But then an act of unparalleled horror tears their family apart, leaving Laurel behind bars and Rosie moved to a different part of the country.

Neither sister has laid eyes on the other since then, during which time their lives have followed very different paths. But now - with Laurel coming up for parole - they look set to be reunited in court, and the world will be watching.
