Anfred is a lost little Norwegian troll who was fast asleep in his favourite spruce tree but awakes to find he has been transported hundreds of miles away to London! Surrounded by the big grey lions in Trafalgar Square, millions of strangers, cars, and bright lights (not to mention the pigeons everywhere), Anfred is afraid. Luckily for him he meets Hudson, a young boy with a nose for adventure… Join Hudson and Anfred on their Christmas Eve journey! Are there trolls living in Trafalgar Square? Will Anfred ever get home?
