Over Sea, Under Stone is a contemporary fantasy novel written for children by the English author Susan Cooper, first published in London by Jonathan Cape in 1965. Cooper wrote four sequels about ten years later, making it the first volume in a series usually called The Dark is Rising (1965 to 1977).In contrast to the rest of the series, it is more a mystery, with traditional fantasy elements mainly the subject of hints later in the narrative. Thus it may ease readers into the fantasy genre.
