The Grinch is a fictional character. He is a green, furry creature who lives on a mountain above the town of Whoville. He hates Christmas and decides to steal all the Christmas - related things from the Whos in Whoville.
I'm not sure specifically as it could be many things. It might be a story about a high school during the winter with a sleigh ride involved, perhaps some adventures or romances that happen during that time at the high school.
Sorry, I don't have the specific name. You might try searching in libraries or online bookstores that specialize in Russian literature. Sometimes, they have detailed catalogs that could help.
I don't know for sure, but they could be typical high school students like the popular girl, the jock, the nerd. Maybe there's a shy student who has a big transformation during the sleigh ride.

The Grinch is purely fictional. It was made up to bring joy and tell a heartwarming tale during the holiday season. There's no basis in real events or people.
