Auzou Book for simon and the great christmas reindeer marathon

It's winter, it's snowing and Simon and his friends don't know what to do to keep themselves busy. As they stroll through the forest, they come across a banner reading: "Grand Marathon des rennes de Noël". Ben, the reindeer, can't believe it! He's finally going to be able to take part in the race he's been dreaming of for so long, and who knows, maybe become Santa's reindeer!
