   Summary

   James Potter has been dating Regulus Black for months, which would already be enough to ruin his life if anyone found out. Unfortunately, that’s not even the worst part.

   Regulus is hiding something dangerous beneath his perfect pureblood image — something with sharp teeth, freezing hands, and a hunger he can barely control anymore. James keeps telling himself he can handle it. That Regulus would never hurt him. That love is enough to survive the kind of darkness growing in the shadows of the war.

   But people are turning up dead, Regulus is getting worse, and James is starting to realize that loving a monster and being loved by one are two very different things.
