The Calculus of Captivity

Captured near the Blackwood territory and mistaken for an elite spy, Dr. Elara Vance is imprisoned in the Iron Bastion's high-security Glass Dungeon. Her captor, Alpha Kaelen Thorne, expects to break a soldier but instead finds himself intellectually ensnared by a woman who deconstructs his defenses with terrifying precision. As a lethal conspiracy breeds within the pack, the line between prisoner and partner blurs, forcing them to rely on each other to survive.
