Father Christmas is ill, and his unexpected successor has a family he refuses to leave behind.
Theo Mercer's December plans are simple: repair a broken Christmas star, attend his daughter's school lantern walk, and keep the promises he has made at home.
Then two elves arrive through a door that should not exist.
They bring an extraordinary revelation: Theo is Father Christmas's son. With Christmas Eve approaching and his father too ill to make the journey, Theo is invited north to learn an impossible profession.
In the hidden city of Borealis, beneath the northern lights, he must master flying reindeer, difficult chimney landings, journeys through solid walls, and a night that stretches beyond ordinary time.
But the oldest rules of the office threaten to separate him from his wife, Mara, and their eight-year-old daughter, Ada. As troubling discoveries emerge among the returning letters, Theo begins to question the traditions everyone expects him to obey.
The greatest journey of his life is approaching. Can he carry Christmas to the world while keeping his promise to come home?
The Man Who Inherited Christmas is a warm, adventurous fantasy about fatherhood, family secrets, second chances, and learning to share an extraordinary responsibility.
