Voidstalker — John Graham

What glitters is gold, but beneath it is rot. Humanity has a sprawling interstellar empire. Advances in science and the resources of countless frontier worlds have brought untold prosperity to its citizens. But how much of this wealth comes from dangerous experiments with alien technology? As an elite intelligence operative, that question plagues Gabriel Thorn constantly. When contact is lost with a mysterious research facility, he is sent to investigate. But he finds a web of secrecy and lies which extends through the corridors of power and industry, and finds himself unprepared to confront the ancient evil buried deep within.
