This story resumes where the first story in this series, Pariah: The End of the Earth left off. The surviving sentients of the destroyed solar system, along with many of the species saved by the cephalopods have fled on a very long journey to Tau Ceti. Now, they must begin rebuilding their worlds. Soon after arriving however, the newly-emerged AI being, Penelope, informs the sentient leaders that she has been invaded by a virus from an advanced alien civilization. The virus is slowly but surely destroying their worlds, as a new battle for survival is initiated. How will the sentient species fight this alien computer virus without the help of their new friend, Penelope?
