Two hundred years ago, neighbouring Yorkshire landowners Miss Lister and Miss Walker find their lives become entwined in a passionate, forbidden relationship and retreat to the Moss House, their private sanctuary away from an unaccepting world. Their tranquillity does not last long as they are drawn into the turmoil of a changing society and a divided family, testing their love for each other, eventually driving them from their home. The world was not yet ready for the likes of Miss Lister. Landowner, scholar, traveller, mountaineer and non-conformist, but in The Moss House we discover her lifelong battle to be her true self as she finds Ann Walker and together they try to live life on their own terms.
