Burke, London, 1963, illus Barbara Crocker
Philippa and Joy are staying with their Aunt Pat at Old Farm, but they soon have to help cousin Mike run the Pony Farm alone. There is competition for the Farm in the shape of Zena Gregson who has turned her riding school into a Welsh Pony Stud, and Philippa and friends are determined Old Farm will not close down. The first foal of the five born is called Golden Boy, a name JMB re-used in one of the Jackie series. She did in fact re-use the entire plot of this book in a later Jackie story.
