Some farms are up in the hills... or down long, winding lanes... but Silver Street Farm is different - it's right in the middle of a town! It's winter and the residents of Lonchester are struggling against the Big Freeze. School is closed, and Meera, Karl and Gemma are delighted. But there's no time to play. Many people in Lonchester find themselves stuck without food. However, with the help of a stranded Russian Ballet company, their sled dog, Boris, and some friendly police dogs, the Silver Street kids come to the rescue of all those in trouble!
