The Graveyard Game (Company) Reprint edition

Mendoza is a Preserver for The Dr. Zeus Company, living in the past to collect species for the future. But when she kills six people in California in 1863, The Company makes her disappear.

Joseph, a senior Preserver, loves Mendoza as the daughter he never had. Drunk on chocolate and fueled by rage, he's determined to find her however long it takes. Being an indestructible, immortal cyborg gives him an unlimited well of patience.

What begins as a rescue mission uncovers a conspiracy stretching across fifty centuries of recorded history. Behind it lie genocide, graveyards filled with Company agents, and the roots of the ominous Silence that falls across the world in 2355.
