A cryptic message. A missing woman. And one man ready to make it personal.

Frank Sherman doesn’t want to be found. But when a message arrives from Ruby—a woman tied to his last blood-soaked mission—he knows he can’t ignore it.

She’s vanished into a remote Idaho town—and whatever she was running from just caught up. The locals won’t talk. One body’s already in the morgue. And the people hunting her aren’t amateurs—they’re pros with money, muscle, and no mercy.

Sherman digs in. Bodies drop. And as the lies tighten around him, he realizes Ruby isn’t the only one being hunted.

Perpetua is the third high-impact installment in the Frank Sherman Thrillers Series—where small-town secrets turn deadly fast, and justice is delivered by a man who never backs down. Fans of Jack Reacher, The Gray Man, and Mitch Rapp will tear through every page.
