Will Judy's lucky penny lead her to the nation's capital – or to C-A-L-A-M-I-T-Y? And what do her spelling-bee nemesis and a pot-bellied pig have to do with it?

The lucky penny in Judy Moody's pocket sure does seem to be working. She can't stop winning – at bowling, spelling, the unbeatable Prize Claw, everything! For sure and absolute positive, she'll ride that wave of good fortune all the way to Washington, DC. Watch out, District of Cool, here comes Judy Moody, the luckiest kid ever, until ... oh no! Her lucky penny just did a belly flop into a porcelain bowl of yucky, blucky UN-luck. Has the coin's magic gone kerflooey? Are some people, like Jessica Finch or Stink, destined to have all the luck, while she, Judy Moody, gets stuck with a garden full of three-not-four-leaf clovers, a squealing pot-bellied pig in an elevator and a squashed penny with cooties? ROAR!
