Pony sledding, apple punch, and a winter midnight party: Christmas time is only this beautiful in Trippelwick! Annelie is thrilled: Although ponies don't actually celebrate Christmas, there is a secret gift exchange at the boarding school for pony whisperers. But then Annelie draws the pony director's name. What on earth should she give him? By chance, she overhears that he has found a clue to the treasure of Countess Trippelwick, who founded the school for pony whisperers. Can Annelie solve the riddle with the help of her friends and her companion pony Henry? Lavishly illustrated with enchanting colored illustrations by Larisa Lauber.
