Synopsis: From Amazon description: "On the First of March 2047, the world changed. Now, thirty-eight years later, while most of the global community struggle to survive, US dominance is preserved by an agency so aggressively secretive that anyone who looks too hard turns up dead. Or worse. The ultimate enforcers of this agency are known as Guardians. You don't get to be a Guardian, you are bred to be a Guardian. In-vitro DNA tweaks make you stronger, faster, and smarter. High-tech implants include a battle computer AI that can control your emotions. And your training covers every act of violence possible, using every weapon imaginable, all so you can deliver overwhelming force on those who threaten the status quo. But the dark tends to secrets, and secrets corrode. As a young Guardian finds when a seemingly routine assignment in San Francisco unexpectedly pivots. With civilians in the firing line, and the body count growing, it seems his enemies are always a step ahead. Taught to see patterns that others miss, the assignment is a jigsaw of missing pieces. Then, just when he thinks there is nothing left to reveal, he suddenly finds himself with no option but to confront the ugly truth at the core of his very being. This is the opening sequence of the 'The Egan Universe', a hard science fiction series spanning hundreds of years of a future for mankind that we hope we never see."
