Dania’s granny lives in an old station building next to a disused railway. Every year Dania, her big sister Nanda and their parents move to their grandmother’s for December in the run-up for Christmas. Granny has become older and more forgetful during the past years, and sometimes she speaks nonsense.

One evening Granny seems exceptionally absentminded before disappearing from her room. The same night Dania hears something and sneaks out to see it with her own eyes: an express train is pulling up at the station.

Dania manages to stop the night train and the adventure begins. She boards the train that returns every night. On the train she meets Konrad, and it soon transpires that everyone on the night train has lost someone they love. With the help of a key from Granny and a mysterious music box, Dania and Konrad are able to bend time itself.

Will the children find their lost loved ones? And who has actually lost whom?

An enchanting and wildly riveting story brimming with the magic of Christmas has 24 chapters and is also splendid for reading out loud.
