A dying tech billionaire hands Zoe Wolfe a device she doesn't understand, and within hours, the people who killed him are hunting her across continents. What begins as a desperate scramble to survive becomes something far more dangerous: a race to understand what she's carrying, who wants it, and why someone is systematically dismantling the infrastructure that holds modern civilization together. From the shores of Lake Geneva to the copper mines of the Atacama, from the backrooms of Cyprus to the high passes of Central Asia, Zoe and a small team of operators, analysts, and oddities must outrun a conspiracy that isn't just trying to win the future - it's trying to make sure no one else has one. Acceptable Range is a fast-paced and frighteningly plausible read that mixes nail-biting action with an unrivaled insider's peek behind the current geopolitical curtain.
