Junie B. is having a run of bad luck, losing every game at the school carnival.  When she finally wins the Cake Walk on her last ticket, she chooses a fruitcake as her prize.  But who in the heck knew that sparkly foil-wrapped fruitcake was really a lethal weapon in disguise?  "The innocent first-person narrative will make lower-school readers laugh out loud at her mispronunciations as they recognize their own confusion and failure."--<i>Booklist </i>
