Snape: and The Long Lost Daughter

This is from the perspective of Madeline Rositas Evans. This is a twist on the original series "Harry Potter" by the one and only J. K. Rowling. I do not own any of the original characters in this book, and the events featured which correlate with the genuine book series are not mine either. I was not called upon any publishers nor commisioned to create this, I have fabricated this on my own accord, separate to any links of the original series "Harry Potter".
Madeline was born a mere 2 days before her Mother, Lily Potter's tragic death. She is the daughter of Severus Snape and yet neither are aware of the existence of one another... Yes, she cheated. Yes that may seem shitty, but this is an alternate reality. Don't like it? Don't read it, but you will. And if you don't? Well, then you'll just have to wait til' my Father hears about this!
