Killer Countdown (Stella Knox #15)

One countdown. One prophecy. Zero second chances.

FBI Agent Stella Knox has faced monsters in every form—serial killers, cult leaders, and the darkest corners of the human soul. So when a millionaire’s home burns and his daughter vanishes, a ransom demand screams textbook kidnapping. Until the girl strolls into the wreckage...and murders a federal agent.

It’s not the end of a case. It’s the beginning of something far worse.

Stella’s team is left reeling. Carved into the agent’s flesh are ancient cuneiform symbols—grotesque signatures that have surfaced at ritualistic crime scenes across the country. Wisconsin. Idaho. New York. And the small Pennsylvania town where Stella thought she helped end a nightmare.

She was wrong.

The Administrator has returned. And he isn’t alone.

His disciples believe the world is ending. That salvation requires sacrifice. And unless Stella and her team can unravel the prophecy and unmask the mastermind behind it, blood will soak the streets...including the blood of those she loves most.

Killer Countdown is the explosive final book in the Stella Knox series by bestselling authors Mary Stone and Stacy O’Hare. The end begins now.
