A Baby-sitters Club graphic novel adapted by New York Times bestselling cartoonist Arley Nopra!

Mallory knows she's a good baby-sitter. She's been looking after
  her seven younger brothers and sisters for years. So when Kristy
  offers her a steady job baby-sitting for the Arnold twins, Mal
  thinks it'll be easy money.


  The twins sure are cute in their matching outfits. But once Mrs.
  Arnold leaves, Marilyn and Carolyn turn into twin terrors! They
  trick Mallory so that she can't tell them apart and they act like
  spoiled brats.


  Taking care of Marilyn and Carolyn is a baby-sitting nightmare.
  But Mallory is a responsible member of the Baby-sitters Club and
  she's not giving up!
