Following Jack's intuition, the team arrives in the Middle East to hunt the Brotherhood of Blood and seek answers to the ever-expanding mystery of the Infection. And answers they do receive, but not without more questions arising as Lance witnesses a deceased team of agents frozen into place beneath the depths of the Persian Gulf. Agents whom he discovers are Jack's former teammates, the long lost Tenebra Lambda.

Their enemy's will proves as threatening as their ally's unsettling past; the Brotherhood has been waiting for them. With Monica and Akumi's lives now hanging in the balance, a high-speed chase ensues through downtown Dubai. Rogue agents of order clash with dark agents of chaos, tales and secrets told to turn a quest for justice into a struggle to survive.
