Clementine

In this first book of the series, Clementine tries to help out her friend Margaret, but ends up in a lot of trouble for it. Things get worse each day of the week, until finally she's worried that Margaret is right: Clementine's parents might consider her "the hard one" in the family. They're up to something mysterious; are they thinking they'd be better off if they only had her little vegetable-named brother, Radish, "the easy one?"
