A rogue tech CEO has quietly built an autonomous robot army and sold the technology to China. When the AI goes rogue during a classified field test, the kill switch — the single line of code that can shut the entire system down — goes missing. The Pentagon has 48 hours before the first AI-controlled engagement begins. After that, the war starts without any human pulling a trigger.

Kailani Priest and Stephen are pulled back in. No official orders. No diplomatic cover. No extraction plan. Their mission: find the kill switch, neutralize the asset, and get out before the first engagement locks them inside a combat zone with no side to stand on.

One line of code. Two operators. The clock is already running.
