Wendy the Witch (Usborne Young Puzzle Adventures)

More about the book

Granny Wendy is only halfway through her Learn to be a Witch Course, and she is not doing very well. In fact, unless she can start performing spells correctly, she might find herself expelled from Spell School altogether and lose her witchy hat and special spellbook. Her two grandchildren, George and Lottie, and her black cat, Felix, set out to help her.
