Ed and the Witchblood — Andrew Fusek Peters

Ed's mother unexpectedly disappears, and soon another woman has moved in and persuaded his father to send Ed to live with his grandad in Shropshire. Ed soon learns of the Witch of Mitchell Fold, who, legend has it, broke a fairy's spell and was buried alive by the villagers. Ed has a supernatural encounter with the witch, and uses his newfound knowledge to confront the local gang of bullies.
