Shadow Box (Outlanders Series #49) Book

The collapse of the hybrid-ruled baronies offers a glimmer of hope for an Earth free from the shackles of the alien race that has subjugated humankind since the dawn of time. But the Annunaki threat remains ominous. For the Cerberus rebels, safeguarding the future of the human race remains daunting...and deadly.

A new and horrific face of the Annunaki legacy appears in the Arizona desert. A shambling humanoid monster preys on human victims, consuming their energy, burning their souls--leaving empty, mindless shells in its wake. Trapped inside this creature, the souls of rogue Igigi, once the treasured slave caste of the Annunaki, seek hosts for their physical rebirth. And no human--perhaps not even the Cerberus rebels--can stop them from reclaiming the planet of their masters for themselves....
