When Group FIfteen assassin Charlie Cooper is ordered to eliminate a rogue Chinese scientist, he’s thrust into a deadly game that stretches from the backstreets of London to the glittering towers of Singapore. The target, Dr. Zhang, holds the key to a breakthrough in genetic engineering that could change the balance of global power. But Cooper isn’t the only one hunting him. Also in pursuit is Vanessa, a former agent and Cooper’s old flame, now working for a ruthless biotech corporation willing to kill for Zhang’s research. As rival agencies and mercenaries close in, Cooper and Vanessa form a fragile alliance that can’t last. Betrayals pile up, bullets fly, and what begins as an extraction becomes a race to stop a bioweapon from falling into the wrong hands. In the world of Group Fifteen, loyalty is a myth and survival is never guaranteed. And Charlie Cooper is about to learn that some secrets are worth killing for—and dying for.
