Masquerade — Janice Harrell

DESPERATELY SEEKING ANN
Here was the good news. The guy Ann-Marie had drooled over from afar for so long had finally noticed her. One day at the ice-cream shop he walked over and asked her for a date.
There was just one teensy problem. Biff thought she was someone else. And that someone was Ann-Marie's neighbor, a girl with quite a reputation around town.
Ann-Amrie didn't know what to do. Well, actually she did -- she wasn't crazy! She accepted Biff's invitation to the movies. She'd have to take care of the minor details later. After all, how often did a chance like this come along?
