At the death of fabled CIA operative Bud (Fisher) Liljigren, field agent Adam Zak and his tech-savvy partner, Dreu Sason, are recruited to lead the Agency’s deep-cover Unit 1. When Fisher’s former lover from his service days in Norway alerts the Unit of renewed secret activity in what was once a WW II Nazi experimental lab, Zak recruits a brilliant but disaffected FBI agent, Janet McIntire, to replace him in the field and lead the investigation. As McIntire inserts herself into the life of Alesund, Norway, as the visiting great-niece of Fisher’s wartime lover, word circulates through the international intelligence community that a weaponized strain of the deadly Marburg virus is on the market to be auctioned to the highest bidder. Following a devastating demonstration of the virus’s phenomenal kill rate, McIntire and the Unit 1 team race international buyers to identify the seller, destroy the Marburg mutation, and prevent a potential global catastrophe.
