For the first time ever Daisy isn't looking forward to the school holidays. She's worried about her best friend Mara, who's ill in hospital. But then, walking her dog in the wood, Daisy spots a group of wild ponies quietly grazing. She is especially drawn to a young silvery-white pony and, as she spends time watching the pony, she starts to feel less alone.
Visiting the pony one day, Daisy runs into James from school. She's worried he'll tease her but instead he has some terrible news. The pony actually belongs to his dad and it's James' job to help look after her. Is Daisy about to lose her new friend?
