Moon Riders 6 - Sand Horse

The friends from Moondance Stables are getting ready for a week-long pony camp. It's taking place by the sea, and their friend Willow is coming too. However, they meet the riders from Storm Stables, who want to get revenge for their defeat at last year's summer camp. What's more, Bea's father doesn't like the horse Bea is riding and wants her to leave Moondance Stables. Her friends must convince him not to make her go. Will a new ally from Storm Stables help them, and will Sandman finally choose Bea as his True Rider?
