Alpha's Misconception

SYNOPSIS 
A slight frown creased Damion's face as he addressed Karen, "Karen, I don't mean to be blunt, but you are mistaken. I have already marked someone else as my Luna" He kept his distance from her, confused by her behavior.
"Hold on a minute. What are you trying to say? I'm not making up stories..." Karen ran her hand through her hair, at a loss for words.

Karen Adams Van Brunt, a formidable hybrid of the Blood Moon Pack, was secretly trained by her parents to master her powers. On her eighteenth birthday, she had her first contact with the outside world. That night, she met her mate, Damion Creek Alejandro, a powerful Alpha of the Golden Paw Pack, where she genuinely confessed her feelings for him. Unfortunately, he rejected her, revealing that he had already marked Luna, who turned out to be her elder sister, Charlotte. That same night, Charlotte's body was found in the woods, with all signs pointing to Karen who had an appointment with her before her death.
Alpha Damion Creek refused to believe that marking Charlotte was a mistake. Instead, he imprisoned Karen behind silver bars to avenge Luna's death.
After suffering in prison without Damion's knowledge, Karen was finally granted release. However, her freedom came with a dangerous condition – accepting Damion's life-threatening ultimatum.
Would she be able to keep this illusive deal, or would failure cause her to seal fate with Damion over an inescapable life-bonding punishment?
