Brad Thor has published two standalone thrillers outside the Scot Harvath series. The Athena Project (2010) features an all-female special operations team drawn from the real-life Delta Force. It was Thor’s attempt to expand beyond a single protagonist while keeping the same fast-paced thriller format.
Cold Zero (2026) is a more recent standalone. Both books sit apart from the Harvath continuity and can be read independently by readers who want to try Thor’s writing without committing to the long-running series.
