Volk's Bane - The Overseer Series, #2

One Hundred years have passed since the Bellster's made their historic test of quantum entanglement and accidentally caused the near annihilation of humanity. A compromise has been reached between humanity, mitochondria, and the AI empire.  Led by the literal and rigid figure known as The Overseer, humanity has changed. Human DNA has been re-sequenced. Genetic abnormalities that have plagued the human race have been eradicated.
The resulting genetic changes have eradicated genetically caused mental, physical illnesses. The survivors live much longer, happier lives. The one hundred thousand or so survivors of the human race have elected a new leader, The Proctor. Under his guidance and with the blessing of The Overseer, direction has been given to recover as much of the rich cultural diversity of the human race as possible.
The priority being in the arts and language. Maricella Vasquez leads the team tasked with that recovery. The human race is calmer now, healthier and more peaceful. As a species we welcome this new way of life. With one defiant exception.  Viktor Roper, the alleged savior of the human race refuses to integrate completely with the new utopian society and lives in the wild. A devastating betrayal has pushed him mentally back to the edge.
Feral and enhanced by genetic manipulation, fueled by rage, Viktor pushes his one hundred and fifty-year old body to its absolute limits and beyond. Wisely, The Overseer has left the Nano-memory retrieving implants in Viktor, in place. Only The Overseer knows his whereabouts, what he is capable of and, just in case, keeps him under close observation. Welcome back to Planet Earth, post AI invasion.
Things are about to get interesting.
