Not Just a Witch

Not Just A Witch is a wonderfully spooky young-fiction title from the award-winning author of Journey to the River Sea, Eva Ibbotson.
'I want you to change the next wicked person you see into a tiger,' demanded Lionel. 'A very large tiger.'
Heckie is not just a witch - she's an animal witch, who wants to make the world a better place by transforming evil people into harmless animals, using her incredible Toe of Transformation and her awesome Knuckle of Power. But when slimy Lionel Knapsack charms Heckie, her magic begins to take a darker direction. Her friends, including a cheese wizard and a boy called Daniel, must come to the rescue . . .
