Wren Calloway took the executive assistant job to escape debt, not to investigate her brilliant and increasingly unstable boss. Theo Marchetti built Vantage Analytics into a four-hundred-million-dollar company, but he never goes home. The lights in his office burn through every night. His emails arrive at 3:17 a.m. Some are genius. Others read like warnings. When Wren discovers that Theo lives inside the corporate tower, she begins tracing the invisible system controlling his schedule, diet, sleep, and emotions. The deeper she goes, the less certain she becomes that Theo is running his company at all. Saving him may require dismantling everything he created. It may also require admitting that his attention toward her is part desire, part dependency, and part algorithm. In a building designed to optimize human behavior, Wren must decide whether love can free someone whose prison knows him better than he knows himself.
