It's 1000 years since nuclear war wiped out civilization in the northern hemisphere. A new breed of people arise who control magnetism, Teslas. Sebastian, an orphan boy, is hunted by strange part-machine, part-human people. His only hope is Melanie, an angry, dying teenage girl dragged into the adventure. She sets out to deliver him to the Steam Academy, even if it’s just to stop him talking. Seb must confront an unknown past and fight against all he believes. And occasionally wash his hair.
