Gwen has wanted a pony for as long as she can remember, but there's no way her parents can afford one. And with a demanding older sister, and younger twin brothers, one with chronic asthma, sometimes what Gwen wants gets forgotten. So Gwen does odd jobs around the neighbourhood - anything that will help add a few pennies to her pony fund. When Gwen is asked to help an elderly neighbour, she can't believe it when she discovers Mrs Tilney owns a pony that needs looking after too! Spending time with Teasel is everything Gwen has dreamed of and they soon share an unbreakable bond. But then Mrs Tilney has a stroke, and everything gets turned upside down. Mrs Tilney moves into residential care and Teasel is packed off to stables far away. Will Gwen ever see her again? Can they find a way back to each other?
