Retribution — Steve Stanton

The follow-up to Reconciliation blends science fiction and suspense in this tale about humans' quest for immortality -- and a son's quest for justice.
 
Mia and Zakariah Davis risked their lives to secure an activated sample of the life-prolonging “Eternal virus” for their teenage son Rix -- and while Zakariah survived, Mia didn't. Overcome by grief, Zakariah is determined to contact her spirit in the afterlife, while Rix wants revenge, no matter the cost.
 
Niko, the teenage clone of Zakariah's dead sister, has received the Eternal virus -- and has been captured by vampires who drain her blood nightly for its rejuvenating effects. Rix intends to help Niko escape. And once they join forces, they will go in search of Mia's murderer . . .
 
This action-packed neo-cyberpunk tale continues the story of Reconciliation, in which “themes of transcendence and family love play out against backdrops of real and virtual worlds” (Publishers Weekly).
