Vanessa Potter is the supposed first child of Lily and James Potter, who disappeared the night Lily and James were killed and Harry became the chosen one. Vanessa lived in an orphanage and then on the streets until Albus Dumbledore and Severus Snape came and found her. What happens when it turns out that Vanessa isn't the daughter of Lily and James, but the daughter of Lily Potter and Severus Snape? How will this play out, and how will Severus Snape raise a five year old little girl?
Also, sorry if this sucks. This is one of my first stories, so it might be a little amateur. Still, hope you like it.
