To a cunning serial killer, FBI Agent Nina Guerrera is the one that got away. Now, he’s back—and ready to finish what he started.
Nina narrowly escaped his clutches at sixteen, and years later, her fierce fighting skills go viral after an attack in a Virginia park. But the video has caught the attention of someone dangerous: the man who abducted her over a decade ago.
Now a twisted internet sensation known as “the Cipher,” he lures Nina into a deadly game, leaving gruesome murders as clues. As the world watches his macabre riddles, Nina, along with profiler Dr. Jeffrey Wade, races against time to stop him.
Can Nina finally outwit the killer, or will she become his next victim?
