Earth is forever changed one dark summer night when tiny alien machines known as nanites drift down from outer space. They transform a normal human into a god-like being known as the Singularity, who drives the remnants of humanity underground and to the brink of extinction. Now Earth's only hope lies in the hands of a rag-tag group of "Specials" -- humans mysteriously immune to the nanites' destructive power. The odds are stacked against them, but will a defector from the other side grant them the edge they need to prevail?
