Shakespearean tragedy!

Jessica Wakefield has landed the starring role in Sweet Valley High's production of Macbeath, and suddenly she's too busy for anyone except Paula Perrine, a timid new transfer student who idolizes her. At first Paula spends all her time fawning over Jessica and helping her prepare for her role. But before long, Paula seems to be better friends with Jessica's crowd than Jessica is.
Jessica is pleased that her new friend is coming out of her shell, but when Paula fails to tell Jessica that she's been made her understudy, Jessica wonders if Paula is trying to steal not only her friends but as her role as Lady Macbeth as well! No one else, not even Jessica's twin, Elizabeth, believes she Paula could do such a thing. Can Jessica convince her friends of the truth before it's too late?

"Jessica, what's wrong?" Sam asked, catching up to her in the parking lot and putting a hand on her shouder.
"What are you doing here?" Jessica demanded, turning to face him. "I thought you had to study tonight!"
"I did have to study. But I didn't expect to get here and find you flirting with Paula behind my back!"
"Flirting? Is that what you think? We were only talking, Jessica."
Jessica hugged herself and stared into the darkness at the other end of the parking lot. "You never look at me that way when we're only talking."
"Jessica, I dont know what's wrong with you lately. You seem to go off the deep end whenever Paula's involved. It's not like you to be so paranoid."
"Sam," said Jessica, trying to remain calm, "I am not paranoid. Paula is trying to sabotage me somehow. You'vr got to believe me!"
"Jessica, you're making me angry. I see what's going on. Your little protege is ready to make her own friends, and you can't handle that."
Sam stalked away, but halfway across the parking lot he turned around and yelled back at her, "What do you want, Jess? To control Paula? She's not your puppet, you know!"
"No," Jessica whispered. "But I may be hers."
