The Hollow Frequency

When a woman's body is found on the derelict Kerr property off Marrow Lane, Deputy Annika Holt breaks protocol and calls in Sloane Marrick, a reclusive outsider with a reputation for hearing what others miss. But by the time the cruiser rolls past the rusted gate, the corpse is gone, the radio has gone silent, and a low, subsonic hum still lingers in the dirt. Annika's sheriff, Elias Vance, wants the case buried before it embarrasses the department. The county coroner, Dr. Reuben Pace, finds no body to examine. And the local journalist, Mara Pell, is already sniffing around for a story nobody wants told. As Sloane digs deeper, she uncovers a string of vanishings tied to an abandoned Cold War listening post, and a signal being broadcast on a frequency no one alive should be able to hear. Janek Voss, the town's reclusive audio engineer, claims he can help her trace it. Dorian Locke, a smooth-talking developer with money and motives buried in the valley, insists she walk away. Hadley Quinn, a grieving mother who lost her daughter to the same silence, will do anything to keep Sloane pointed at the truth. With Tobias Reeve circling the case from the DA's office and Dr. Lisbeth Corday warning her that the signal is changing, Sloane must decide how far she's willing to follow the hum, because the hollow is listening back, and it already knows her name.
