Felix and Conor Quinn are brothers at odds. After starting life as a less-than-ethical government experiment, the brothers now share the same body. When their adoptive father, illegal trades mogul Rian Connell, receives a tip that his niece is in danger, he sends Felix to track her down. The assignment brings up bad memories for Felix. It also threatens to bring Conor’s dark secrets to light—secrets that necessitate the manufacture of a drug to suppress his genome.

More pressing problems arise once Felix finds Kaitlyn. He soon realizes that Government Directive International (GDI)—one of the last governments of post-War 2042—has disturbing plans for him. By the time Felix realizes that Kaitlyn was only bait to lure him in, it’s already too late. GDI’s Agent-in-Charge doses Felix with a lethal, fast-acting virus, bringing Conor to the surface. 

Immune to Felix’s virus thanks to his genomic difference, Conor must take up the mantle of uncovering the secrets of his past … before they get everyone around him killed. Every instinct tells Conor to run like hell, but in the end, his only choice may be to outsmart GDI. Or bring the organization crashing down.
