Sickly

My family is far from normal.
Not the type in movies and books about a vampire or werewolf family.
We have money. Actually more than enough. We're rich. Filthy rich.
My parents kill. My grandparents also kill when they were still alive. But they don't just kill for money.
No. We have more than enough of that.
My parents including me kill and murder. Not for money.
But for fun.
