Cinderella herself did not have her life more completely changed than Maggie, when she was whisked by a "fairy godmother" out of an orphanage and off to South West Africa to spend a long holiday in a fairy-tale castle. There was a Prince Charming too --but there the fairytale let Maggie down, for he did not appear to have any interest in her at ail!
