Three women. They have nothing in common. They are different ages, come from different background, and lead drastically different lives. The only thing that binds them together is their red hair—and that each of them has been targeted for murder.

When each 'Red' receives a chilling letter in the mail from a killer known only as the Wolf, their lives are upended as they spend every waking moment in the fear that their lives could be snuffed out at any moment. The Wolf is stalking them, biding his time, waiting for the perfect moment to complete his master plan. Yet the one thing this cunning and devious killer didn't plan for is the Reds discovering each other.

The three women, using clues left by the Wolf, manage to band together in the hopes of protecting one another from this deadly predator. With law enforcement turning their backs on the Reds, their only hope for survival is to turn the tables, for the prey to become the predators. In a riveting game of cat-and-mouse, the Reds must track down the Wolf himself--before he silences each of them forever.
