Imagine if Snape had a daughter, her mother being Lily Evans, born the same day as Harry, making her and Harry Potter twin siblings. Well, Lily Renae Snape is Snape's daughter, also a Ravenclaw...not knowing much of her past or her family yet as her father just wants to protect her and teach her the ways of the wizarding world. This is her first year at Hogwarts and her first meeting with Harry Potter; will she know that there is something about him? Will she figured it out that they are related? Will she confront her father about her mother and her past? And what about the dark lord, when he returns, will he hunt her down as well as Harry? All this and more as Lily's years at Hogwarts all start with...the first year.
