On a planet where the very ground you walk on is electrified, the soil charger race rules, and the humans are dying off. Tage is neither since he is half human, half soil charger-a freak of nature. His only chance for redemption lies in the mission the human elders tasked him with as a boy. Tage has spent his life undercover in the capital city of Currentgrad. By day, he trains to be a soil charger knight-elite warriors who can harness the electricity in the earth into their own bodies. By night, he prepares for his ultimate task: to assassinate the tyrannical Overlord. His only comfort in these dangerous times is Capacity, the only girl he has ever loved, and his small group of loyal friends.
For the humans, the planet has become nearly unlivable. They've built a fortress on top of a rubber sea and have done their best to survive. They've only managed to escape total extinction due to their special skill set that the Overlord needs. Knowing the only way to end the oppression is by taking out the Overlord, they're forced to plan an assassination.
Tage's world is turned upside down, leaving him banished from Currentgrad and left for dead. His friends are scattered and Capacity is missing. Tage burns for revenge, and in killing the Overlord, he'll save the humans and get the vengeance he's craving. At age sixteen, he finally realizes the benefits of being both soil charger and human. His power is unlike anything anyone has ever seen. Can Tage harness the power hiding in his blood? He just hopes it's enough to take on an entire army with his friends and save the humans.
