Mutation — Michael McBride

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 rainforest, 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.
