FREQUENCY

Raya lost her career to a signature she never saw coming. Sirin's signature.

Eighteen months later, Sirin is at her door before sunrise with a classified file and no apology. Three women are dead. Their phones were left broadcasting live. Buried inside the static, in a frequency almost no one alive could find, is a voice playing backwards.

Raya finds it in forty minutes.

Now she is inside a case that connects to the program that destroyed her, working beside the woman who destroyed her, and someone has already written her name into the signal.
The most dangerous thing in the room is not the killer.

It is how much she is starting to need the sound of Sirin breathing in the dark.
