The seat of the Trelawney family for over 800 years, Trelawney Castle was once the jewel of the Cornish coast.

Each successive Earl spent with abandon, turning the house and grounds into a sprawling, extravagant palimpsest of wings, turrets and follies. But recent generations have been better at spending than making money. Now living in isolated penury, unable to communicate with each other or the rest of the world, the family are running out of options.

Three unexpected events will hasten their demise: the sudden appearance of a new relation, an illegitimate, headstrong, beautiful girl; an unscrupulous American hedge fund manager determined to exact revenge; and the crash of 2008. A love story and social satire set in the parallel and seemingly unconnected worlds of the British aristocracy and high finance, House of Trelawney is also the story of lost and found friendships between three women. One of them will die; another will discover her vocation; and the third will find love.
