Jesper Jinx is eleven, and probably the unluckiest person in all of Puffington Hill. Everything he touches seems to end up in sweet disaster. Hence his nickname 'Jinx'.This time around, it is Puffington Hill itself that appears to be jinxed. The school canteen gets shut down and children are forced to eat wild clover flowers for lunch. Horrible hairy acorns fall from the sky, targeting black cats and squirrels. An eyewitness even claims to have seen a flying antique piano.Something utterly peculiar is going on.And it is up to you, Dear Reader, to help Jesper figure out who's responsible for these seemingly unrelated incidents. Could it be Jesper himself? Or Lenny and Benny, the WARRIOR MOUSE brothers? Or even you yourself, the unsuspecting Book Gobbler?
