Pepe by CabbaK reviews
Lily's visions always get her into trouble. More than a year ago, she'd had a trembling vision that sent her to Egypt to figure out the strange memory. But that's not what this story is about. This time though, she's in New York. Luckily, James is with her for the ride. Even if that means getting involved with the mother of a missing baby who's not a wizard. Prequel to Pumki.
