Over a decade after joining the Teslanauts, Raymond Calvert is now a veteran agent in a world changed by the Great Depression. Funding has dried up, once-powerful volt-tech organizations have collapsed, and Electropolis, the secret island city built as a haven for scientific freedom, has been abandoned, its technology left broken and forgotten. Despite the turmoil, Raymond and his wife Helen continue their work in the shadows while raising their family. To protect their children, they’ve made one strict rule: to never go on missions together. One of them must always make it home.

That rule is about to be tested. Nikola Tesla has uncovered an alarming new threat in the ruins of Electropolis: an anomalous energy source growing stronger by the day. Volt-tech factions converge on the island, each hoping to claim its power for themselves. But as Raymond and Helen discover, this energy is not a simple resource to be harvested. It is brilliant, furious, and vengeful. From the island’s discarded machines and lingering minds, an artificial intelligence has emerged, a willful and malevolent force desperate to escape its prison. As rival factions close in and the Anomaly’s power grows, Raymond and Helen are forced into a mission unlike any they’ve faced before, one that will challenge their training, their partnership, and the future of volt-tech itself. What truly haunts the ruins of Tesla Island? And will the world be ready for what comes if it is unleashed?
