*Dark Union* continues the gripping narrative of Court Gentry, a character Greaney introduced in 2009. Gentry is portrayed as a former CIA operative entangled in high-stakes global intrigue. In the upcoming novel, the plot thickens when Gentry, who has long believed he is the sole survivor of his family, encounters a shocking apparition: his late brother at their father’s funeral.

The most recent entry in the series, *The Hard Line*, was published in February 2026, which demonstrates Greaney’s continual commitment to his craft and his audience.
The popularity of the series led to a successful adaptation into a Netflix film in 2022, featuring prominent stars such as Ryan Gosling and Chris Evans. The film’s reception was positive, which has prompted Netflix to announce a sequel, expected to bring back Gosling alongside directors Joe and Anthony Russo. This film adaptation signifies a broader interest in the stories Greaney has crafted, bridging the gap between literature and on-screen entertainment.
