Penance

Vampire, werewolf, Djinn, Phoenix, Shapeshifter, and Witch.
They all came from somewhere.
Six humans started the ritual, six supernaturals walked away.
But they left behind the one person who could destroy them all.
Reese.
Now she seeks revenge on those who stole their power from her body.
She seeks her children.
For they will pay the ultimate penance.
