The past made her a survivor. This case will make her a target. After surviving a violent childhood tragedy and building a career hunting the monsters who shaped her past, one reckless night nearly ended everything. Now, two years later, Agent Ava Cortes is buried in the CBI’s white‑collar division—until her former boss pulls her back into the world that almost destroyed her. Special Agent August Blake has four victims and no leads. Desperate to stop the next murder, he turns to the one person he trusts to see what others miss. Brilliant, relentless, and infuriatingly intuitive, Ava can crack the case. But will she be fast enough? The investigation turns into a deadly race for survival when an early snowstorm traps everyone in the small town of Black Oak. Including the killer. But they're not the only hunter on the mountain.

The symbols point to a killer. The truth points to something far worse. Back on the CBI’s Priority Investigations Team, Ava is settling into her new position when she gets a call from an old colleague with the Oceanside Police Department. A former confidential informant of hers was found murdered, his body stuffed into a blue oil drum. In Ava's home turf. When she arrives at the scene, the strange symbols etched onto the body seem to connect to two other victims found months prior. As the tendrils of the case pull Ava further into the fray, she discovers a tangled web of psychological warfare, gruesome rituals, and murderous beliefs that put the beach city’s most vulnerable at risk. With tourists flooding in for the Fourth of July holiday, the press creating panic, and the killer two steps ahead, Ava must fight the ghosts of her past to save the next victim. But what if there’s more than one killer at work?

With the killer barreling toward a spectacular finale, her team in shambles, and another victim hanging in the balance, Ava must decipher the clues that set the murders in motion before their final act. This killer doesn't want Ava on his trail. He wants her in the front row.
