Trudi Adendorff lives in an orphanage all her life, until the day she completes her matric and an unknown benefactor sends her to university. He is Jacques de Villiers, a handsome businessman, and his only requirements are: she must not know his name and she must write to him regularly about her progress. However, he never writes back.
