Under the shadow of the Orb, Peter, a renowned computer scientist, is desperate to discover who murdered his daughter and why. The authorities believe it was suicide and have closed the case. With no clues, Peter uses his skills to resurrect his daughter, who directs him to Zip, a sixty-year-old woman who has recently been medically transplanted into the corpse of a teenager. After decades of blood and war, Zip just wants to have fun. Peter wants to prove his daughter didn’t commit suicide. Together, their search for the killer will reveal the awful truth of the Orb. A revelation so shocking it brings the cold war between Orb Industries and the Church to boiling point, threatening a global conflagration.
