On the farm where Julie lives there are cows and chickens, but no ponies. With her whole heart, Julie longs for a pony of her own. And she has a plan. Every summer on Chincoteague Island, there is an auction of ponies who have swum across the channel from Assateague, where ponies run free. If Julie works hard and saves her money all year, perhaps she can win the pony of her dreams--her very own Chincoteague pony.
