He promises to repay her kindness – all she has to do is make a wish.

Three years later, a devastated Madge escapes war-torn London with her two children for a dilapidated house in Dorset. She is crippled with grief at the news her husband has been lost over the channel, but determined to give Lily and Cyril the best Christmas ever.

The Arwells are surprised to be greeted by a madcap caretaker whose mysterious Christmas gift leads them into a magical wintry world. Here, Madge will learn how to be braver than she ever thought possible. And that wishes can come true…
