Whizz! Pop! Granny, Stop! by Tracey Corderoy
There is more trouble afoot for the little girl whose granny is (still whisper it) a witch, whom we first met in Hubble Bubble, Granny Trouble. Granny just loves to help - a little bit of magic always speeds things along - and she's happy to whizz out her "helping kit"at the drop of a pointy hat. However, sometimes all her granddaughter wants is to do things under her own steam, and to spend some quality time - well, normal(ish) time - with her beloved granny. But is her birthday party the right time to choose to turn down the magic?
