What would you do if your own memories were stolen from you? What would it mean to live a life not even knowing who you truly are? Years ago, Mason Kane and Nadia Sinh were among the most elite agents of Citadel, but a mysterious and dangerous operation erased all memory of their past missions, their skills, and even their personal lives. Separated from everything they once knew, they were forced to live new identities, unaware of the dangerous world they had left behind. Now, as dark and sinister forces from their past reemerge, Mason and Nadia are pulled back into a world of espionage, intrigue, and life-threatening missions. With the guidance of the brilliant spymaster Bernard Orlick, the two former lovers must confront the fragments of their erased memories, relearn the skills that made them unstoppable, and face enemies who know them better than they know themselves. As they navigate a maze of deception, betrayal, and hidden truths, Mason and Nadia must race against time to piece together their past before it’s too late—and ultimately save not only themselves, but the future that hangs in the balance.
