The Truth Hurts — Leslie Goldman

Sabrina cannot tell a lie....

When Sabrina casts an honesty spell on her classmates, it backfires. Now Sabrina's the one who has to tell the truth, the whole truth, and nothing but the truth, for the next forty-eight hours! Not only does Sabrina offend her friends, but she also manages to tell her housemates that Salem really can talk.

Having her housemates think she's gone off the deep end is the least of Sabrina's problems. She's supposed to be cat-sitting Salem while her aunts are on vacation, but he's disappeared without a trace -- and there's no way Sabrina can bend the truth to get out of this one!
