Following where the previous book left off, Michael is held by tribe of natives. During this time, he meets a new Glow: Tessa, known before as Tesla, who escaped from Hatch. She is able to increase the powers of the other electric children. Michael is soon told he and Tessa are going to meet Jaime, the man who helped the Electroclan in the previous book. As they depart, Tessa has a tearful goodbye with one of the tribal women whom she calls her mother. Jaime takes them to his base camp where they are ambushed by Elgen guards. As Michael, Tessa, and Jamie are attacked, the native tribe that helped Michael and Tessa is wiped out by Dr. Hatch's Elgen guards. Michael is forced to kill the guards with the camp's security system to evade capture. Jaime, Tessa, and Michael destroy the camp and hike away to prevent the Elgen from learning anything.
Meanwhile, Taylor and the rest of the Electroclan have been captured by the Peruvian authorities for destroying the Elgen's power plant. While being interrogated, Taylor inadvertently tells the Elgen about the voice that has been helping them. Ostin leads an escape attempt, but the group is captured by Elgen agents and then re-captured by the Peruvians.
After extensive hiking, Michael, Tessa, and Jaime set a trap to disrupt the convoy carrying the rest of the Electroclan. Michael manages to stop the convoy and frees everyone but Taylor and Jack who were taken by an Elgen bounty hunter. The Electroclan rescues them, but Wade is killed by a stray Elgen Guard. After an improvised memorial service, the Electroclan goes to a hotel to meet Jaime.
Jaime takes them to a safe house where they are told that the Hatch plans to use the Elgen fleet to take over a small island country and from there build an arsenal of EMPs to take over the world. The Electroclan is to destroy the fleet's flagship: the Ampere. However, Ian, Zeus, Abigail, and Tessa, who are tired of running, decide to leave. Michael, Taylor, Ostin, McKenna, and Jack attack the "Ampere" but are cornered in the ship's engine room. As they prepare to detonate the bomb manually, the Elgen attack ship, the Watt explodes and Tessa, Zeus, Abigail, and Ian return. The Ampere is then blown up while everyone escapes.
During a celebration for the mission's success, Taylor and Michael award Wade the Electroclan Medal of Valor to commemorate his sacrifice and to ease a grieving Jack. Jaime allows Michael and Ostin to talk to their parents. The joy is cut short when it is revealed that Hatch escaped the ship before it blew and has kidnapped a child prodigy in China, known as Jade Dragon, who has figured out how to fix the MEI machine and create more electric children.
