Broken by Zara Novak

She’s mine. She’s my mate. Now I just have to keep her alive.
As a Guardian I’ve got better things to do than babysit a human. I’m a vampire super-soldier. Looking after some ditzy little doctor is far below my pay grade. But then I realize just what’s in store. A powerful magical artifact. A lost treasure.
Doctor Rachel Stone doesn’t realize it just yet, but when she uncovers the Halo amulet, she unearths a whole world of trouble. Every vampire in the world would give his left arm to possess the amulet and the infinite power it can gift.
Now we’ve got one week to return the amulet before the world is broken forever. During that time I’ve got to keep my mate alive and teach her a thing or two about discipline.
Luckily for her I’m a gifted teacher. It won’t be long before my firm hand has her screaming for more. Every sin will be punished. I will tame her with the sting of obedience. She’ll beg. She’ll feel shame. I’ve got a long, hard, lesson for her…
By the time we’re finished she’ll be broken.
