Six centuries of history drew Kate Armstrong to Cassillis House in Ayrshire. Originally from Australia, Kate has always had the dream of owning a castle and she picked one that was in a desperate condition. A four-year struggle began to restore 110 rooms - but not only was Kate attempting to save the fabric of the building, she took on the responsibility of preserving the story of the Kennedy Clan who called Cassillis their home for 21 generations. While the new owner discovers waterlogged kitchens and hidden rooms, the historical investigation reveals the building's transition from defensive fort to pleasure palace. Will the weight of history and the scale of the task be too much for Kate and her army of restorers to save it?
