Las gemelas de Sweet Valley

Amy's pen pal from San Francisco, Samantha, shows up for the weekend. After Sam is introduced to a popular group of girls, she tells a lot of exciting stories. But are they true or not? Jessica decides to find out.

Jessica has always prided herself on being the more sophisticated twin, but suddenly it's her sister, Elizabet, who's blossoming.

The Unicorns don't want Mandy to join their group and they want Jessica to tell her she can't join them. Then Mandy gets some news that makes the Unicorns seem unimportant.

Elizabeth is happy to hear her best friend Amy will be staying with her for a while, but soon Amy is spending all her time with Jessica and telling Elizabeth's biggest secrets.

Jessica has to start wearing glasses. She is convinced the Unicorns will drop her the second they see her and Aaron will change his mind about their date. Should she spend her life in her room?.

Identical twins Elizabet and Jessica are on different teams in a special schoolwide contest to decide what will be buried in a time capsule.

Jessica comes up with a plan to convince her parents they're being unfair in declaring a new club off-limits.

After a disagreement with her sister, Jessica decides to start her own class newspaper but finds the school isn't big enough for two newspapers.

Jessica and Elisabet learn a secret language from their father called Ithig. Jessica gives the secret language to a friend and now it is not a secret anymore--in fact the whole school knows it.

The twins suspect their mother is in love with a strange man. How else can they explain her hushed phone calls and mysterious trips?.
