Jill's Ponies: Black Boy and Rapide

This is the eighth book in Jemma Spark's Jill series which is a follow-on from the original Jill books by Ruby Ferguson. This book is not narrated by Jill herself and begins with the lives of Black Boy and Rapide, her ponies when she was a child. Black Boy belongs to Lavender Ellison-Heath, whose social climbing mother wants her to win in gymkhanas so that she can gain entry into the county set. Rapide belongs to Morgan Pevensy, the youngest child of the Duke and Duchess of Tolkington. Morgan's life is blighted by being born into a horsey family and not fitting in. She doesn't mind ponies and riding, but she is not horse-made like the others.
