After saving Tara and Jack—and losing a few of their own—in a dramatic battle in the Peruvian jungle against the Elgen offshoot the Chasqui, the Electroclan has returned to the US to regroup. But their downtime is brief, as Abi—who was abducted from outside her college dorm—is still missing.

Piecing together what few clues they have from video footage of the abduction as well as some additional information from Grace, whose consciousness has broken free of her physical body and connected with worldwide intelligence, they determine that she is being held somewhere in Peru by the leader of a group of other electrics known as the Colony. And so—once again joining forced with Alpha Team for a dual-pronged attack—they return to South America for a rescue mission.

They’ve fought—and won—against incredible odds before. But they’ve never had to face off against others with powers similar to—and potentially stronger—than their own. Still, with the life of one of the Electroclan members at stake, failure is simply not an option as they take on their final mission.
