A book about real girls - and real horses. All Kim wants is a pony of her own. But when her parents buy Diablo, she gets more than she bargained for. Diablo likes hay and world domination, in that order - and he hates going on trail rides. As if that wasn't bad enough, Kim also has an annoying big brother and a rival at the equestrian centre who seems to have everything that she doesn't. On the bright side, Diablo can talk. He has plenty to say, but most of it isn't very nice. Can Kim turn her pony - and her big brother - into better-behaved beasts, or will she become another victim of the Great Pony Buying Disaster?
