Damson Delaney has never met anyone like Samuel Heron before. Not only is he part of the Travelling community, he also believes in magic, faeries and ghosts. Stranger still, he’s convinced that his horse, Mara, is bewitched, as she carries a crescent moon marking on her forehead. At first Damson doesn’t believe Samuel’s stories. But then the nightmares start and frightening things begin to happen - things she can’t explain. When Samuel vanishes, Damson has no choice but to tame the bewitched horse and embark on a terrifying ride into darkness to find him. But before she can save her friend, Damson must unlock the mystery of an ancient and terrible curse.
