The Christmas tree is back! Here is the fourth book by Best-Selling Author Tom Fletcher, about the Incredible Adventures of Risdosaurus and his best friend William Trandle, who once again have to save Christmas.

However, this time the holiday is under threat because of a character from a different story! And not the same, but the well-known Dickens cake Ebenezer Scrooge. Who better than him can ruin the whole Christmas mood? After all, from the very sight of him, garlands go out and needles fall from the Christmas trees. It is not easy to overcome such an opponent, but William, his sister Brenda, his father and even Santa himself take up the task! But will they be able to overcome the anti-Christmas magic?
