My Scary Fairy Godmother by Rose Impey
'Everyone should have a fairy godmother - if ever a girl needed one it was me.'
When Isabella's mum becomes ill, Isabella has to go and live with her scary but glamorous cousin, Maxine. Maxine takes one look at mousy little Isabella and knows exactly what she needs - a complete makeover. At first, Maxine seems like one scary fairy godmother to Isabella, but as Izzy takes on the new identity Maxine has forged for her, she finds she is beginning to enjoy it...a little too much. Even Maxine isn't prepared for the monstrous results of her makeover!
