Katy's life has never been so busy. She has to take care of three Exmoor ponies at the same time: her first and dearest four-legged friend, Karamella, her partner Jacko, and their foal, the energetic little Kanga. And her best friend, Alice, gets a wonderful prize-winning pony as a gift, so they go riding together a lot. In addition, he will have a new neighbor, James, who helps more and more with the ponies, but after a while it seems that the horses help the autistic boy even more. When Katy first hears about loagilty, she has no idea how much she can help her friends by accepting this special challenge.
