Pure Sin by Laney Clover

When The Meld came, it merged all of us together: ethereal, fae, spawn, and human. Except for a powerful few, like the Pure. They think because they make the rules they’re above them. They’re not.

I’m only thirteen years old when the Pure takes me. I’m just a regular—a human and fae girl with a muddied background. I’ve got a little shadow-fae ability, but I’m no match for a 100% human—a Pure. He’s our monarch. A king of the city who rules with a bloody fist. No one says no to him and survives.
I run away with my sister, and I have a daughter. Raine is my whole world. We’re happy in our new town. No one knows what I really am. Who Raine is to me. Until they come…
Raine
Seven years ago my world ended. A Pure and his angel visited our town and killed everyone. Including my family. I should have died with the others. But I’m too stubborn, too different, to go away quietly. I return to the city of my mother’s birth. Paradise. And I watch and learn. I study the monarch’s minions, those who really run the city. I don’t care how powerful they might be. Or how monstrous they really are. I’ll either go around the Four, or I’ll kill them.
Because nothing will stop me from getting my vengeance on the man who killed my family.
And no vampire, werewolf, fae, or…whatever the big guy is…is going to stop me.
