After learning about the American Revolution, Judy Moody's in the mood for liberty and freedom - freedom from her parents' rules and her pesky little brother, that is. But will Judy be able to prove that she's ready for a bit more independence? When Judy meets Tori, an English girl, at the Boston "Tea Party" ship, she learns that Tori enjoys far more liberties than she does, including her own phone, private loo and lots of pocket money. So Judy embarks on a quest for more independence. But when staging her own Boston tea party doesn't work, she is forced into retreat ... until a real-life crisis gives Judy a chance to prove her independence, once and for all.
