Though we like to imagine Harry having a twin or Snape having a daughter of his own, what if those worlds intertwined and we got Andi. The half sister of Harry Potter and daughter of Severus Snape. She is also the only child to ever be created through use of magic (as in spells and potions). Her goal is to blend in but to feel loved. Read as she follows Harry through his Hogwarts experience up until the end.
