A brief vacation trip to a beautiful oceanside mansion in Mexico is turned into a nightmare by a mysterious plot for revenge.

    They belong to a boy, a boy who has not seemed remarkable until now. And Helen--terrified, but intrigued--is drawn to him. The fact that he is in a body and she is not presents this unlikely couple with their first challenge. But as the lovers struggle to find a way to be together, they begin to discover the secrets of their former lives and of the young people they come to possess.

    Her dad is making her spend the whole summer volunteering at the local soup kitchen.The truth is she wishes she was the care-free party-girl everyone thinks she is.She pretends it's all fine. That her "perfect" family is fine. But it's not. And no one notices the lie...until she meets Flynn. He's the only one who really sees her. The only one who listens.The truth is that Jess is falling apart – and no one seems to care. But Flynn is the definition of "the wrong side of the tracks." When Jess's parents look at him they only see the differences-not how much they need each other. They don't get that the person who shouldn't fit in your world... might just be the one to make you feel like you belong.

    They're both popular, smart, and gorgeous, but that's where the similarity ends. Elizabeth is friendly, outgoing, and sincere—nothing like her snobbish and conniving twin. Jessica gets what she wants—at school, with friends, and especially with boys. This time, Jessica has set her sights on Todd Wilkins, the handsome star of the basketball team—the one boy that Elizabeth really likes. Elizabeth doesn't want to lose him, but what Jessica wants, Jessica usually gets ... even if it ends up hurting her sister. Meet the Wakefield twins, their guys, and the rest of the gang at Sweet Valley High....
