The Zeroes are in disarray.

One of them has vanished. One of them is in prison. The rest are on the most-wanted list. And something big is brewing.

Accused of murdering Swarm, Bellwether is in a high-security prison, isolated and unable to use his powers of influence. Flicker, Crash, Mob, and Scam are on the run as suspected domestic terrorists. And Agent Phan of the FBI has a secret weapon up his sleeve?a teenager with a superpower that the Zeroes haven't encountered yet.

After a daring breakout, the group is drawn to New Orleans, where celebrating Mardi Gras crowds promise enormous power to anyone who can channel it. There, an army of Zeroes is gathering around a charismatic leader?whose plans are nothing short of cataclysmic.

Time is running out for the Zeroes, but they must learn to trust one another again if they want to avert the looming disaster.
