Right in front of me was a terrifying, silver-haired wolf-beastman Admiral, completely losing his mind to a lethal biological heat cycle.

Angel was slammed onto the freezing stone slabs of the central square, surrounded by the deafening, mocking laughter of her clan. Her own sister, Jasmine, stood over her with a look of pure malice, loudly and falsely accusing Angel of sneaking into the Chief's tent to seduce him. Then, Al Stein, the man who had sworn to be her mate, stepped out of the crowd with a twisted face of disgust. "You're a genetic reject. You can't give me children. You're useless." He threw their bone mate ring hard at her face, cutting her cheek, as the crowd roared for her blood.

"You're the expert, you can handle it." He then took my satellite phone, shoved me into a hastily dug snow pit, and left me to die. His new girlfriend, Kelsi, appeared, wrapped snugly in my shimmering smart blanket. She smiled as she used my own ice axe to slash my suit, my last layer of protection against the storm. "Stop being so dramatic," he told me, his voice full of contempt as I lay there freezing to death. They thought they had taken everything. They thought they had won. But they didn't know about the secret emergency beacon I had stitched into my sleeve. And with my last ounce of strength, I activated it.

"Give me one reason, Liv." He stalked toward me, cornering me against the edge of the desk. "One good reason why I shouldn't bend you over this desk and fuck you senseless." My breath caught.
