Follett`s latest is a bio-thriller taking place over a wintry Christmas holiday in northern Scotland and well larded with family drama. Toni Gallo is the driven head of security for Oxenford Medical (aka the Kremlin), a research facility working on a cure for Madoba-2, an especially virulent strain of Ebola. She also has a running feud with her ex, a local cop, and is pestered by the attentions of newsman Carl. But she really wants to be with her widower boss, Stanley, whose daughter Olga`s husband, Hugo, is paying unwelcome attention to his sister-in-law, Miranda, herself in uneasy love with a milquetoast boyfriend, Ned, whose daughter, Sophie, is the object of young Craig`s budding affections. It is not until midnight on Christmas Eve that all this soap is rinsed away, and the plot kicks into high gear, as a band of desperate, violent thieves, led by Stanley`s wastrel son, Kit, lay siege to the well-defended Kremlin in the midst of a terrible blizzard. Predictably, things go suddenly, frightfully wrong.
