When a vicious murderer resurfaces and starts a killing spree to wipe out those who put him behind bars, one thing becomes clear: defense attorney Brynn Holloran, who helped prosecute him, needs to run for her life. When the police come up empty-handed, Brynn turns to a private security firm for protection. But when she defies advice and gets involved in the investigation, even the former Secret Service agent assigned to protect her may not be able to keep her safe. With every new clue she discovers, Brynn is pulled back into the vortex of a disturbing case from her past. As the clock ticks down on a manhunt, Brynn’s desperate search for the truth unearths long-buried secrets and reignites a killer’s fury.

While on leave from her job, police detective Andrea Finch gets an urgent call from her younger brother. Her search for answers takes her to a dusty Texas border town where danger lurks in plain sight. FBI agent Jon North is working undercover in west Texas investigating an unsolved murder that may be linked to a broader plot. But when the evidence points to Andrea’s brother, Jon finds that persuading the stubborn cop to help will be harder than cracking his toughest case.
