Bell, Book and Candle
One day he walks into her African art gallery.  He asks to make a telephone call (after Gillian's aunt put a spell on his phone and broke it). Gillian learns Shep is about to marry an old college enemy of hers, Merle Kittridge. Gil and Pyewacket take revenge by casting a spell on Shep, so he has to fall in love with her. She eventually falls in love with him too. She must make a choice, because witches who fall in love lose their supernatural powers. When she decides to love Shep, Gillian's cat and animal spirit, Pyewacket, becomes angry and leaves.
