For Ali Reynolds, the first Christmas without her father is riddled with grief and uncertainty. And with her husband and founding partner of High Noon Enterprises, B. Simpson, anxiously preoccupied by an upcoming New Year’s trip to London, she is ready for a break. But when Stu Ramey barges into her home with grave news about a serious—though suspicious—accident on the highway to Phoenix involving the car in which B. was riding, things take a turn for the worse. At the hospital, a groggy, post-op B. insists that Ali take his place at a ransomware conference in London, as troubles brimming around High Noon come to light. But questions remain: Who would go to such lengths to remove the tech company from the picture? And how can Ali be sure she and the rest of the team aren’t also in danger? In a race against time, Ali must assemble the pieces of a puzzle, woven with vendettas she never could have imagined, all before she and the people she loves become collateral damage.
