Book excerpt: There is a tradition in Jiggy's hometown - the night before a boy starts school he goes to the Piddle Pool near the old quarry and pees in the pool for good luck. But when Jiggy went...he couldn't go, and he's been unlucky ever since. Now Jiggy wants to change his luck. One night, while he is mid-piddle, a genie rises out of the water. Will the genie bring Jiggy good luck, or is Jiggy's life about to get even worse?
