Thirty Six - Critical Point

Catherine Vale returns to Zurich —to find the predictive architecture she designed years ago has resurfaced inside a private research facility, changed into something she no longer recognizes, something that doesn't just predict what people will do but decides how to make them do it. The only way in is Adrian Keller, the one man who never stopped wanting her back, and Catherine knows exactly what it will cost her to use that. Six months after leaving Brian, it isn't a mission so much as a slow unraveling, moving through corporate secrets, foreign intelligence, and a system that was never meant to think for itself, each step forward costing her something she can't get back. An ocean away, Brian is learning that walking away from her was never as simple as he told himself it was. Some systems can be shut down. Some choices can't be undone.
