A new adventure with the beloved Christmas dragon Spekulatius. It's Advent time again, and Mats and his sister Matilda are looking forward to baking cookies, candlelight, and maybe even the first snow. But this year, the pre-Christmas season is anything but festive and is quite chaotic! Why does the Advent wreath suddenly smell like vinegar? And why is everyone in a bad mood? Mats and Matilda agree that only Spekulatius can help. The little Christmas dragon has flown back home to Christmas Island after their last adventure, but now he rushes to the children's aid. He has a suspicion about who might be responsible for the Christmas chaos: someone who can't stand Christmas. The perfect gift for the Advent season: a cheerful and colorful Christmas adventure in 24 chapters. Ideal for reading aloud, richly illustrated.
