Frostfire.

"Frostfire" by Elly MacKay is a children's book about two foxes, Celeste and Miriam, who go on a seasonal walk and encounter a mythical snow dragon. Miriam, the older sister, describes the dragon's attributes, including its collection of snowy "diamond dust" and its ability to create "frostfire" on windows with its fiery breath. The story highlights the bravery of the younger sister, who reassures Miriam that she is not a princess but a queen and is very brave. The book features beautiful mixed-media paper scenes with sparkling photographs, making it an enchanting winter tale for children ages 3-7. [Extracted from the article]
