It's summertime in Smallbridge, but, as always, nothing exciting is happening. Smallbridge doesn't do excitement. They do gossip, though. And now Elsie Pickles is the subject of the gossip as rumours spring up about her new magic skills ...

Soon the town is overrun with witches, much to the annoyance of the magic-hating people of Smallbridge! But maybe a little bit of magic is just the thing Smallbridge needs?
