The Dragon and the Moon

Draco Malfoy doesn't know what he believes anymore. He doesn't know if he cares about the dealings of mudbloods and half-bloods and blood traitors and blood purity. All he knows is that he once saved his parents from certain death, and now he is determined to save them from the entirety of the Wizarding world. Only this time he is entirely on his own.

In which Draco is an angsty prat, the family feels are strong, the politics are complicated, and Luna Lovegood is basically an angel.
