Miss Impossible

Malia, Dot, and Bree have landed the best-paying babysitting gig they've ever seen, so they're thrilled, at least until they arrive and find out their client is Zelda Hooper. Zelda has been the girls' rival since preschool, and she is definitely not a baby. The job is too lucrative to give up, so the three friends have to get through it, even though the situation is far from what they expected.

Zelda, who should be the one embarrassed that girls her own age are being paid to watch her, instead enjoys teasing them in her own home. The story asks whether she is truly villainous or simply misunderstood, and the sitters must decide how to handle her while keeping their cool.

This is the third book in the Best Babysitters Ever series. It returns familiar characters, including those readers love to dislike, and focuses on the importance of friendship. It is aimed at fans of Rachel Vail and Sarah Mlynowski.
