Meet Mary-Kate and Ashley, the Tween Queen Twins! Your new best friends have just arrived . . .
Ashley can't wait to go back to school. The new school year means shopping for new clothes, meeting new boys . . . shopping for more new clothes! Her twin sister, Mary-Kate, thinks she's crazy. Mary-Kate would much rather hit a softball than a mega-mall. But they do agree on one thing: They're way too old for a babysitter!
Too bad their dad doesn't see it that way. Now the twins need a plan - a plan to show Dad just how right they are!
