Books like Sixth Grade Secrets

From the Newbery-award winning author of HolesWhen Laura Sibbie starts a secret club at school, makes the other members them give her something totally embarrassing as "insurance," to make sure they don't tell anyone else about the club. She promises to keep the insurance secret, unless someone blabs. Gabriel, who never tells on anybody, would be a perfect member of Pig City. He wants to join, too. But when Laura asks him, something goes terribly wrong. Now there are two secret clubs in Mr. Doyle's class, and guess who's the head of the new one-Gabriel! Each club is determined to topple the other, and nobody's secrets are safe.
