Secret correspondents . . .

Jessica Wakefield is sure that her newest get-rich-quick scheme is the perfect way to make a little extra money that she badly needs. Even her twin sister, Elizabeth, loves Jessica's latest idea: a letter-writing service for people who don't want to write their own. Elizabeth agrees to write the letters in exchange for half the profits, which she plans to spend on a special gift for her boyfriend, Todd Wilkins.
But this "perfect" money-making solution turns into a nightmare when Jessica reads a girl's request for love letter - to Todd! Jessica knows that Elizabeth has been neglecting Todd lately, and she's afraid that Todd might leave Elizabeth for a more attentive girlfriend if given the opportunity.
Can Jessica find a way to save Elizabeth and Todd's relationship and the letter-writing business, too?

"How is that letter-writing service going?" Mr. Wakefield asked.
Elizabeth smiled tiredly and flopped doen on the sofa. "Well, it's been incredibly lucrative, but Jessica and I both feel that the letter-writing business takes too much time away from the other things we do, like homework and seeing our friends. We know we need to slow down." Elizabeth folded her arms across her chest. "I'm just not sure what we're going to do."
Elizabeth picked up the U.S Sports catalogue and flipped automatically to the warmup jacket she had ordered for Todd. It was due to arrive any day now, and whe she could tell him what had been keeping her so busy. But for some reason, Elizabeth felt malancholy. She glanced quickly at her parents, contentadly sharing an evening together just reading and talking, and she thought about how little she had seen Todd during the past weeks. Somehow, her plan didn't seem worth it anymore. "Right now," she said, surprising herself with the firmeness of her tone, "I'm ready to quit altogether."
