Isla and her friends are growing up fast. Emily s legs are too long for her to carry on riding Zippy; and Isla s pony, Dusty, is for sale! When Tilly, Calvin and Emily are introduced to cross country riding, their instructor, Sian, suggests Emily rides Echo, a tall, chestnut mare. So Emily has to learn to ride a different pony, while Isla tries to find Dusty the perfect next home. The Awelon Tyn Stories follows the lives and learning of the children and ponies at Awelon Tyn Stables.
