Caroline has decided she wants a career in show ponies, and her cousins decide she is the ideal person to show Clytie, their show hack. Caroline is not so sure. Then Benjamin, the show pony from hell, is stolen by thieves who have not the faintest idea of just what they have taken on.
NB: despite the publishing date, this is the first story in the series. It’s basically the series as first published in Pony Magazine.
