When his family moves to Gullywith Farm in the Lake District, Olly just can’t imagine being happy in his new home. Gullywith is the coldest house in the world and no one has lived there for years. Then Olly meets KK and she tells him locals won’t go near the place. It does seem to be jinxed - the roof falls in, walls collapse ... but most strange of all, Olly notices that there are stones at Gullywith that can move around of their own accord. Stones with peculiar ancient markings on them. He feels sure that they are angry about something.
