The Reset is coming back—and this time, it’s personal. After surviving his first trip into Tartaria, Cal Morton wakes with fragments of impossible architecture burned into his mind. Drawn into a covert war against the Bureau, he trains under the Preservers to stop a second Reset before it wipes away the last traces of the old world. But a voice from the past someone he thought lost forces Cal into choices that put his life, his allies, and the future of humanity at risk. As the Bureau’s plans accelerate, the battle to close an unstable observatory gate becomes a fight to survive the bleed-through between worlds.
