Kaleidoscope Century

Joshua Ali Quare wakes in 2019 at the age of 140 in a strong youthful body with no memory of his past, to find he is at the center of a vast and deadly conspiracy. The only clues to his identity are the records he has left--messages from the man he once was...
As Quare journeys through his past, he discovers he has been a key figure in the history of a turbulent, violent century--soldier, criminal, assassin, spy. A century filled with killing plagues and warring cults, ruthless corporations and dying nations. A century where treachery is often the only way to survive.
Now someone is looking for him. Someone from his past. And Quare must learn the terrifying secret of his history before it unleashed devastating consequences for the future of the human race.
The author the Nebula-nominated Orbital Resonance now tells a darker, more harrowing tale of future war, social breakdown, and one man's struggle to survive. A man with a tailored virus which causes him to become desperately ill every 15 years manages to live through the entire 21st century. For each time he recovers from the illness, he has no memory of his previous life--but is physically 10 years younger.
