Garrett Mann Books in Order

Garrett Mann leads one of Konkoly's newer thriller lines, and the setup is blunt from the start. Mann is an FBI special agent running ARTEMIS, a task force focused on cartel-related killings in the Southwest. He knows violence. He knows how ugly the borderland cases can get. Then one investigation opens onto something much larger.

Five dismembered bodies are only the beginning.

The first book, A Clean Kill, starts like a violent procedural and then swerves into conspiracy thriller territory. Mann and his team think they are hunting a particular kind of killer. Instead, they start uncovering a structure that reaches beyond cartel brutality into covert sites, organized training programs, and people with political protection. That wider frame carries into A Hired Kill and A True Kill.

What makes this series feel a little different from Konkoly's others is the blend. There is FBI procedure here, yes, but not in a cozy or forensic-heavy way. The books move with military-thriller energy. Raids, chase sequences, field operations, and tactical violence all matter. Mann may wear a Bureau badge, but the world around him is crowded with sicarios, hidden compounds, compromised officials, and enemies who are willing to use state-level resources to stay buried.

The geography helps. Rural roads, border corridors, New Mexico facilities, and other hard edges of the American Southwest give the series a rough, exposed atmosphere. This is not a polished Washington conspiracy seen from conference rooms. It is bodies in the dirt first, explanations later.

Mann himself is driven, suspicious, and not especially suited to looking away once he has seen the pattern. As the books go on, his task force, and later close allies, become more important because the central question stops being who committed one crime. It becomes who is building the larger machine and why.

The tone is muscular and restless. If you want a thriller that starts with murder investigation and keeps escalating until federal law enforcement is effectively fighting hidden cabals, this is what the Garrett Mann books are offering.

Konkoly likes people who keep pushing even when every sane signal says stop. Garrett Mann belongs in that group.
