Lyra Potter and the Philosopher's Stone

This book is dedicated to @PrinceOfNight14

Everyone knows the story of Harry Potter-the Boy Who Lived, the Chosen One, the savior of the wizarding world.
But nobody notices Lyra Potter.
As Harry's twin sister, Lyra has spent her entire life living as the "spare" in the cupboard under the stairs. While Harry runs on pure instinct and dangerous emotions, Lyra relies on her sharp wit, cynical sarcasm and a strict rule of self-preservation. She doesn't want to be a hero; she just wants to survive.
But when the twins arrive at Hogwarts, the script gets completely flipped. While Harry is ushered into Gryffindor to fulfill his golden destiny, the Sorting Hat takes one look inside Lyra's brilliant, calculating mind and yells: SLYTHERIN!
Suddenly, the "spare" Potter is dropped into the snake pit. Surrounded by suspicious purebloods like Draco Malfoy-who immediately decides he hates her guts-and under the watchful, haunted eye of Professor Snape, Lyra has to play a dangerous game. But beneath the cold green banners, she might just find something her brother already has: a family of her own. Armed with a Beater's bat and a devastatingly sharp tongue, Lyra Potter is about to prove that the shadows are a lot more fun than the spotlight.

I don't own Harry Potter all right reserved to the respectful owners.
I do own Lyra, Evelyn (Severus Snape's wife) and Vesper and some changes to the plot!
Eventual Draco x OC
I will be following the books instead of the movies so yes there will be hyphens!
