Joe and the Lightning Pony by Victoria Eveleigh

Joe is delighted that his pony, Lightning, is brilliant at mounted games. The two of them make a great pair and Joe can't wait for them to try out for the Prince Phillip Cup team. There's just one problem - Lightning seems quite small now that Joe is growing so fast. What will he do when he's too big to ride her? And what will happen to Lightning if she is sold?
