This book was written specially for Julip Model Horses and was sold only by them. It is an adventure featuring several of the models in the Julip Horse of the Year range of the time, including, of course, Sundance.
Sundance, Jigsaw, Midnight and Silver Cloud, with their riders Sarah, Jack, Mandy and Nicky are going on a 20-mile sponsored ride to raise money for charity. They are all looking forward to it, but after only a few miles, everything starts to go wrong, and Midnight is left with an injured leg.
