Sixteen-year-old Anna should not have been born. It is the year 2140 and people can live for ever. No one wants another mouth to feed, so she lives in a Surplus Hall, where unwanted children go to learn valuable lessons - at least she wasn't put down at birth.
One day, a new inmate arrives. Anna's life is thrown into chaos. He says things about her parents and the Outside that couldn't possibly be true... Or could they?
