On the cliffs of the Cornish coast stands an ancient mansion that looks more like an abandoned crypt than a family nest. Some of the large Penmar family love him passionately, to the point of obsession, while others hate him with all their hearts, and each has their own reasons for this. The Penmare Inheritance, a house riven by family strife, chronicles three generations, from the Victorian era to the Second World War, with the cruel laws of history reflected in the events of human life as if in a mirror. Epochs, morals, and principles change, but only the Penmare castle remains unshakable. Will this Inheritance bring happiness to any of them?
