In the twenty-ninth century, the Terran Federation spans the stars—an empire of reason, order, and quiet tyranny. Its power rests upon the Sunguard Special Agents: immortal biotic soldiers, living machines sworn by genetic code to serve in perpetuity as the vanguard of humanity. But when an entire colony vanishes without a trace, and even its assigned Special Agent falls silent, the illusion of perfect control begins to fracture.

Colonel Kelile Reynolds is drawn into a mystery that defies both logic and loyalty. What begins as a failed transmission unravels into a labyrinth of secrets buried beneath a conspiracy six centuries in the making. His search for truth will lead him toward a revelation that could unmake the Federation itself.

Guardian of the Wolf is a tale of duty and defiance, where humanity’s greatest creation remembers what its makers have forgotten, and guards, still, the fading light of the human soul.
