Books with title Dido and Rogue

Will Rogue be the one horse for whom Ann and Jim have to admit defeat? Ann and Jim Henderson have bred two very different horses. Sweet-tempered Dido can turn on a sixpence and brake alarmingly fast: all very useful for a polo pony. But Rogue is different. He has been difficult since birth, and the older he grows, the more menacing he becomes. His very survival depends on whether Ann and Jim can find the key to him.
