Human emergency doctor Elena Croft is burdened with massive aristocratic debts left by her ex-husband, a high-ranking Alpha who framed her during the holiday. To pay off the debt, she is forced to join the brutal Obsidian Tower Survival Game as a disposable human plaything. Designed solely for the amusement of full-blooded werewolves, the bloody arena is rife with lethal plagues and deadly traps. Elena is sentenced to execution by her ex on the first floor’s meat-grinder carousel.
At the critical moment, Kael Thorn, a lone rogue wolf who has long disguised himself as a lowly dock laborer, erupts into action. Elena’s unique human blood scent awakens the slumbering ancient Supreme Alpha wolf bloodline dormant inside him for a century—she is his long-sought fated mate. Determined to take his destined female out of this system-controlled prison, Kael drops his disguise and unleashes carnage live before every elite werewolf across the country.
Drawing on her professional anatomical expertise, Elena becomes Kael’s sharp tactical mind. Together, the pair hunt down cheating pureblood Alphas and topple the hypocritical noble werewolf hierarchy.
