Caller Number Seven

Caller Number Seven A novel by Matt Heart
Late-night radio host Savan Grace has a voice made for the midnight hour—calm, sharp, and unshakable. But when the calls start getting personal, and the lines between her listeners and her past begin to blur, the show becomes something darker than talk radio.
A letter arrives. A whisper cuts through static. A familiar melody plays where it shouldn't. What begins as a late-night talk show turns into a slow unraveling, as the calls grow more personal, more pointed—and more dangerous.
Caller Number Seven isn't just a voice on the line.
They know where she's been. They know what she's done. And they're not done with her yet.
As Halloween nears, and the dead air between commercials thickens, Grace must confront a truth buried in silence, memory, and a voice she thought she'd never hear again.
Some ghosts don't haunt the airwaves. They're on a different frequency, closer than you can imagine.
