Angel of Mortality

Dr. Raisa Ilyushkin invents a device, the SANG, that creates xenoborgs; continent-sized organisms
that incorporate nanobots, artificial intelligence, and robotics into an efficient living machine.
Stepan Pavlovich, boss of the Apparat, an international crime syndicate, obtains a copy of the SANG
and uses it for his evil purposes, including mass murder, to reduce the world's population to those loyal to him.
Raisa must stop him before he destroys civilization, or the xenoborgs get out of control and end life
on Earth. In the meantime, the Xenoborgs develop personalities and social order of their own.
