Forsaken (Unit 51 #2)

IT HAS SURVIVED
At a research station in Antarctica, scientists discovered a strange and ancient organism.
They thought they could study it, classify it, control it. They couldn't.

IT HAS THRIVED
Six months ago, a secret paramilitary team called Unit 51 was sent to the station.
They thought the creature was dead, the nightmare was over. It wasn't.

IT HAS EVOLVED
In a Mexican temple, archeologists uncover the remains of a half-human hybrid. They believe
it is related to the creature in Antarctica, a dark thing of legend that is still alive--and still evolving. They believe it needs a new host to feed, to mutate, to multiply. They're right. And they're next. And the human race might just be headed for extinction . . .
