Roxy & Jones: The Curse of the Gingerbread Witch by Angela Woolfe

Roxy Humperdinck is still reeling from the Great Fairy Tale Cover-up when Cinderella Jones returns with a new mission: to investigate The Missing – the children who followed the Pied Piper into the mountain thirty years ago, never to be seen again. And so begins another crazy adventure that takes the girls up Jack’s beanstalk, through Red Riding Hood’s Woods … and to the cottage of the most evil villain of all time, the Gingerbread Witch.
