This book was written as part of a four-book commission for Collins’s Spitfire books imprint, under the author name Jane Eliot. Jacky was later reprinted (and I think expanded) in the Collins Pony Library.
Jacky has been promised that she can jump the black mare Flicka, but then Miss Henderson has to sell up the riding school. Celia Grunter, who is certain to ruin Flicka, wants her too. At first, nothing seems as if it’s going Jacky’s way.
