Which witch wins?

Sabrina is determined to make it on mortal terms in the Teen Work Weekend project at the mall... even if she does use a little magic to land a job at the Too Chic Boutique. But Libby and her friends, Jo and Cici, are out to make her look like a fool and suddenly her magic isn't working!

Sabrina soon learns the reason: her newfound cousin Tanya, a full witch who swears she'll prove that her magic is stronger than Sabrina's. Even if it means threatening Sabrina's job and casting a spell over Harvey, too. But every time Sabrina tries to strike back, her spells boomerang and she's in worse shape than before. Her aunts say she must learn how to protect herself. This time she's on her own....
