The Christmasaurus
by Tom Fletcher

William Trundle, a dinosaur-obsessed boy in a wheelchair, unknowingly asks Santa for the one thing that doesn't exist: a dinosaur. But deep in the North Pole, a lonely dinosaur is about to make William's impossible wish come true.
Series background & context
Mixing the festive season with prehistoric reptiles might sound like a strange combination on paper. However, Tom Fletcher proves that these two worlds belong together in The Christmasaurus. This series has quickly become a modern holiday staple, sitting comfortably alongside classic tales of reindeer and elves. It takes the standard North Pole mythology and injects it with a heavy dose of imagination, rock-star energy, and genuine heart.
At the center of the story is William Trundle, a young boy with a boundless obsession for dinosaurs and a dad named Bob who loves Christmas just as much. William uses a wheelchair, but the narrative ensures this is just one aspect of his life rather than his defining trait. On the other side of the world, hidden away in the snowy drifts of the North Pole, lives the Christmasaurus. He is the only dinosaur in existence, hatched from a frozen egg by Santa Claus himself.
Like William, this dinosaur feels a bit out of place among the reindeer and dreams of something more. When these two lonely souls finally cross paths on Christmas Eve, it kicks off an impossible friendship. They bond over their differences and their shared need for connection. The books manage to balance the fantastical elements with grounded, real-world emotion.
It gets surprisingly deep.
William deals with difficulties at school, including a bully named Brenda Payne, and the lingering sadness of losing his mother. The story treats these challenges with respect, showing that kindness is often the bravest choice a hero can make. Of course, it isn't all serious reflection. The adventures ramp up quickly, pitting the duo against villains like the Hunter, a man obsessed with mounting the last dinosaur on his wall.
As the series expands, the lore grows richer. The universe introduces the Winter Witch, a powerful and mysterious figure who controls the flow of time within the North Pole. Later installments see William and his prehistoric best friend trying to save the holiday from the Naughty List itself. The stakes get higher with each book, moving from personal battles to missions that involve saving Christmas from being canceled entirely.
What really sets these books apart is the musical DNA woven through the pages. With Fletcher's background in songwriting, music acts as a core language of the series. The elves don’t just work; they sing in rhyme. The storytelling has a rhythmic, cinematic quality that makes it feel like you are reading an animated movie. It is loud, colorful, and full of spectacle, yet it never loses sight of the quiet moments between a father and son.
Ultimately, this is a celebration of the impossible. It reminds us that the best kind of magic isn't just flying sleighs or time-stopping spells, but the courage to believe in yourself.
