There's no other horse quite like Calliope. She's short. She's slow. She's lumpy. She's a rhinoceros. Still, Cowboy Boyd has a real strong belief in Calliope and her ability to help out the crew at the Double R Ranch. Boyd and Calliope try to prove themselves to the ranchers by rounding up strays and hauling posts, but it just doesn't look like it's going to work out. That is, until a storm drives all the cattle away from the ranch. They need someone real special to bring them back. . . .

Lisa Moser brings her trademark humor and strong structure to this smart and silly story of a cowboy and his beloved steed-a rhinoceros.
