TrekWar - Raymond Bradley

Enter Jake, a cynical investigator holding his deteriorating, seventy-percent cybernetic body together on borrowed time. Hired to uncover who contaminated the supply, Jake is dragged into a cosmic conspiracy governed by nine godlike syndicates who treat humanity not as peers, but as product.

Guided by a mortalized, unraveling entity known as Q, Jake rescues Sarahh-a synthetic clone whose bloodstream harbors the sole immune code against the contagion. Hunted across orbital space by syndicate enforcers and betrayed by lunar bio-architects, Jake must navigate deadly run paths and forge a desperate pact to save a dying species.

To end the epidemic, Jake must pay the ultimate price to reprogram humanity's future before the clock runs out on every beating heart and glowing core.
