Widowed, pregnant Lady Demelza Mandeville returns to her family home, Trengrouse Hall, after her husband’s recent death, dreading meeting family friend, Sir Denzell Kelynack, who jilted her in her first Season.

Denzell looks forward to the meeting—he wants to know why Demelza had jilted him eight years ago. And what role did his needy, unstable mother play in that?

Finding out the truth, and finding a path to a new life, is complicated by Demelza’s pregnancy. If the baby is a boy, she’ll be bound to the Mandeville estates until he’s an adult; if a girl, she’s free to live her own life while a Mandeville cousin inherits the estate.

The Trengrouse Ball is a promise of things to come, but will the promise come true at Christmas?
