High hooves the quest of the warrior sheep

Summary: "A silver object falls mysteriously from teh sky and lands on Sal, a matronly Southdown ewe who lives happily with her sheep friends on Eppingham Far. The sheep are convinced that an ancient ovine prophecy is being fulfilled. They must go North (so to Scotland, perhaps?), on a mission to aid Lord Aires, Sheep of all Sheepdom, Ram of Rams, in his battle against the powers of darness in the shape of Lambad the Bad. Thus the Eppingham Posse of Rare Breed Warriors is born. In fact, the silver object is a mobile phone, dropped from a hot air balloon by Luke and Neil, who have been stealing bank money over the internet. They need that phone back to hide the evidence. and a couple of woolbags aren't going to stand in their way! The chase is on."--Web page.
