Joe's garden has been invaded by fairies and he's totally fed up. Since prim, girly cousin Sara-Jane arrived to stay with Joe and his sisters, the climbing frame's become a fairy bower, there's fairy cakes for tea and no one wants to do his assault course any more.
Then Joe meets the new neighbour - another girl, to his horror. But Mel shows more interest in boat battles and croquet than wings and gossamer - and she has a splendid idea for putting the fairies to flight for good.
