More than she can handle . . .

Jessica Wakefield can't wait for the school fair - until she gets stuck being in charge of water-baloon booth. Who wants to be drenched by every kid in Sweet Valley Middle School? So when her twin sister, Elizabeth, is offered a baby-sitting job that day, Jessica sees the perfect opportunity to steal the job away and stick her sister with the water-baloon booth.
But Jessica's plan backfires. The kid's she baby-sits turn out to be real monsters. The minute their parents leave, they begin tearing up the house - and her! Jessica needs help fast. But will Elizabeth feel too betrayed and too wet to come to her sister's aid?

"I'm going to Kill Her!"

"I'm absolutley positively going to kill her," Elizabeth seethed.
"Good. She deserves it," Amy said. "She's making things worse and worse! First she steals you baby-sitting job, and then she sticks you with the worst possible booth in the entire fair!"
Elizabeth just kept shaking her head. "My very own sister. How could she do this to me?" Jessica had gotten her into difficult situations before, but this one had to be worst.
"I'm going to find her right now," Elizabeth said furiously. "I'm not kidding, Amy. There's no way that Jessica's going to get away with this!"
