If you haven't already and are around central London tomorrow (Sunday the 30th), take a stroll down to Trafalgar Square and go see "Journey". An art installation that tells the true story of a young girl who was promised the world and ended up branded and shackled (not literally but may as well be) ... and sold as a prostitute.
You walk through seeing, hearing and smelling most of the things she had to go through and at the end hear her story.
This is really touching, hits home, makes you think and definitely is worth checking out. The last day is Sunday 30th Sept (sorry for the short notice, I only got to check it out today).
The Helen Bamber Foundation are behind it and there's work by Mode 2 on the side.
