Harry Potter was the Boy Who Lived. His twin sister was the Girl Who Died. Except nobody told her she was supposed to stay dead. Fifteen years ago, Voldemort murdered James and Lily Potter. Their son survived. Their daughter didn’t. At least, that’s what everyone believes. Because somewhere in the dungeons of Hogwarts, Y/N Lupin is very much alive—and blissfully unaware that she’s supposed to be dead. As far as she knows, she’s Remus Lupin’s daughter, Sirius Black’s honorary niece, and just another Slytherin trying to survive sixth year with eight chaotic best friends and a dangerously complicated relationship with Mattheo Riddle. Her biggest problems should be unfinished assignments, questionable pranks, and figuring out what exactly she and Mattheo are. Not discovering that her entire life was built around a secret. Not learning that Harry Potter is her twin brother. And certainly not finding out that her almost-boyfriend’s father is the man who killed her. The wizarding world remembers the Boy Who Lived. It’s about to remember the Girl Who Died.
