When research scientist Samantha Bryton comes to the aid of a stranger who washes up on the beach near her home, she is unaware that he is the result of an experiment conducted by Charon, a practitioner of illegal robotics and android research, and finds herself on the run from a deadly criminal, with only an underground group of rogue AIs and androids that can help.
