Mallory on Strike — Ann M. Martin

Mallory couldn't imagine not being in a big family like hers. There's always someone to do things with, and she likes to help take care of her younger brothers and sisters.

But now Mallory's working on an important writing project, and she needs peace and quiet. So why won't everyone leave her alone? Nicky needs help tying his shoes, Claire wants a sandwich, and someone has to break up the fight among the triplets.

Mallory feels like a baby-sitting slave.

And there's only one thing to do: This Baby-sitter going on strike!
