Mutation (Unit 51‪)‬

IT LIVES.

In a research hangar in Virginia, a Unit 51 team studies an ancient but long-dormant virus that can transform human physiology—and turn it into something else . . .

IT MUTATES.

In the Amazon rain forest, a newly evolving life form known as Subject Z acquires the ability to think conceptually, build elaborate traps, create new carriers—and spawn a new race . . .

IT SPREADS.

In Mexico and Turkey, the men and women of Unit 51 race to uncover a global link between the mutations: a connection as ancient as the oldest tombs on earth—and as alien and unknowable as the universe itself. But time is running out. The infected are growing in number. And the nightmare is going viral.
