Too Late, Alpha: I'm Dead

I volunteer to be the mate of Carl Wood, the Alpha of the Nightfall pack, as a direct measure to resolve the conflict between our two packs. He marks me on a full moon night. His gaze is so fervent in that moment that I interpret his look as a genuine sign of his attraction. Carl personally leads the elite fighters across the border two years later. He grabs my head, making me witness the gruesome dismantling of my mother, father, and brother by the pack; his gaze is alight with vengeful satisfaction. "Did your father show mercy during our youth when he destroyed my pack, Aria? Do you truly believe that having you here is enough to make up for this vengeance?" Carl assumes the position as the most powerful Alpha of the northern region, with Selena Hall established at his side as his Luna. I am kept barely alive, imprisoned in the depths of the dungeon in the pack. If I attempt to end my life, Carl retrieves the bones of a relative from the cemetery and incinerates them right in front of me, bellowing with bloodshot eyes, "You're not allowed to die unless I allow you to, Aria!" I immediately cease all resistance after that. Carl's heart was pierced by a silver-tipped arrow during his escape years ago. I had to implore the dark witch to use dark magic and substitute my sound heart for his. There are only three days left before the poison completely takes hold of me.
