Alien predators attack Europe. A deadly virus spawns an epidemic. And a clandestine organization conspires to profit from chaos and forge a new world order.

In this heart-pounding finale of the award-winning H.A.L.F. series, Tex, Erika, and the rest are in a race against time. They fought for their lives. Now they battle to save our species.

Tex and Erika are fugitives and running for their lives. But when Tex falls gravely ill, a Navajo healer is his only hope for survival. Tex emerges from the ordeal changed in body and mind and with vital information: how to stop the predatory M’Uktah from overtaking the human population and destroying those he has come to love.

Erika Holt seeks a respite from the constant threats to her life, but she’s not about to give up. As she and Tex launch a mission to shut down the intra-galactic highway used by invaders who prey on humans, she grows closer to her troubled half-human companion. But what about her on-again, off-again boyfriend, Jack?

Jack Wilson, with his friend Anna Sturgis, is on a mission of his own. He’s determined to destroy The Makers, an illuminati-like organization behind the H.A.L.F. program. It’s time to put an end to their schemes for world domination. Complicating matters, an anti-viral that could save millions from an alien virus has been stolen.

As both alien and human forces line up against them, the destiny of all mankind is in the hands of these young warriors. And time is running out.
