A Pure-Blood's Burden

Lyra is Regulus Black's twin and Sirius Black's younger sister but she hates Sirius for leaving her and Regulus behind. Now Regulus is a death eater, Sirius left them, all her cousins are married off or disowned, and now she is left with nothing from her old happy life.

This story takes place right before the wizarding war and up until after the war is over. There are definitely some love interests so don't be worried but I would mostly like to focus on the main plot and Lyra's story and how she discovers who she is.
