From international bestselling author Carolyn Arnold comes a gripping FBI thriller that will have rookie Special Agent Brandon Fisher hunting a ritualistic serial killer whose killing spree is far from over.

Eleven Rooms. Ten Bodies. One Empty Grave.

When Brandon Fisher joins the FBI’s Behavioral Analysis Unit, he knows he’ll face the country’s most dangerous killers. But nothing prepares him for his first case.

Dispatched to Salt Lick, Kentucky, Brandon and his team uncover an underground bunker containing eleven circular graves. Ten hold the mutilated remains of victims, buried in a ritualistic fashion. The eleventh grave is freshly dug—and waiting.

With the property owner already behind bars, Brandon is convinced an apprentice is still carrying out the killer’s twisted work. As the investigation stretches across the United States, every new lead confirms one terrifying truth: the murders are far from over.

Then Brandon realizes the killer has turned their attention to him. If the FBI can’t stop the next murder in time, victim number eleven may be Brandon—or his wife.

Perfect for fans of relentless serial killer thrillers, criminal profiling, and edge-of-your-seat suspense. Readers who enjoy Jeffery Deaver, Chris Carter, and Brian Shea will love this gripping FBI thriller.
