Sequel to: Swarm.

After the shocking conclusion to Swarm, the zeroes are scattered, on the run, and desperate. They're up against challenges from within and from the world around them, and one thing is certain an epic showdown is guaranteed.

Accused of murdering Swarm, Bellwether is in a high-security prison; Flicker, Crash, Mob, and Scam are on the run as suspected domestic terrorists. Meanwhile an army of Zeroes is gathering in New Orleans, around Piper-- a new Zero with powers unknown. But the group faces internal threats, too. Can they learn to trust one another, before an apolocalyptic event occurs?
