Secret plans . . .

When Cara Walker announces that she and her mother are moving to London, no one is more shocked than Steven Wakefield. After losing his first love, Tricia Martin, to leukemia, Steven can't bear the thought of losing another girlfriend.
Jessica Wakefield knows a way for Cara to stay in Sweet Valley - as her brother's bride! Steven thinks an elopement is the perfect solution, and at first Cara aggrees. Then Cara begins to wonder if she's ready to sacrafice her future to stay with Steven now.
Does Cara have the courage to follow her heart - no matter what it's telling her?

Cara took a deep, shaky breath. She looked straight ahead at the line of the hills rather than at Steven. "The real reason we went to London was because Mom was being considered for a big promotion."
"Well, that's great. Isn't it?"
"You don't understand," she told him. "A promotion - and a transfer."
"A transfer?"
"They called her on Monday, after we got back to Sweet Valley. She got the job in the London office. She starts in three weeks." Cara's voice dropped to a whisper. "Steven, my mother an I - we're moving to London."
Slowly, Cara turned to face Steven. He stared back at her, but he couldn't speak or move his hands to touch her. It was as if the shock had drained all the power from his body, all the blood from his heart.
Finally, he managed to stutter, "You can't. You can't go."
"Do you think I want to?" Cara cried.
Steven reached for Cara. He held her as tightly as he could, but even so he felt as if she were already slipping through his fingers.
