Animals always come first for Mandy Hope, and at Animal Ark - her parents' busy veterinary surgery - Mandy is always making new friends.
Mandy is delighted when her dad wins first prize in the Christmas raffle. He's going to own a racehorse for a day! Bright Spark is the most beautiful thoroughbred that Mandy and James have ever seen. But he is famous for hating the rain, and the forecast for race day is gloomy . . .
