Science and Magic

Cecilia Frobisher is a muggle who has been employed by Dumbledore to work on a potion for Harry to defeat Voldemort. What happens when she is forced to work with Snape? There is a completed sequel to this fic and also I'm halfway through the last story as of Sept 2016. And, because they so rarely happen these days, I do appreciate it when I get reviews - thank you in advance :)
