To save Casterglass, all the Penryn children will need to return home, rebuild their lives among the ruins, and find love that has proved elusive...

The Penryn family have always been eccentric—living in a dilapidated castle in the wilds of Cumbria with an orchid-mad father and a classicist mother who likes to re-enact Greek myths, who wouldn't be? Penniless and proud, patriarch Walter Penryn resists selling his birthright and family legacy until taxes, bills, and the need for a new roof force him to reconsider.

Well-heeled Londoner Althea Penryn doesn't expect a divorce and job hunt over the Christmas holidays, but her husband claims he's done and the prenup is solid. She packs up her reluctant teenage children and heads home to Casterglass Castle to confront the ghosts of her past—including the real one her mother claims lives in the old guard tower. And then there's her unexpected romance with local sheep farmer, John Braithwaite, who is everything her adulterous, solicitor ex-husband isn't.

This Christmas, amid the renovation and potential heartbreak of losing her family home, can Althea find a new purpose and the happiness that has so long eluded her?
