When he sleeps, the hunt begins. FBI Profiler Ryker Townsend is a rising star in Quantico’s Behavioral Analysis Unit, but his dark secret could cost him his career. When he sleeps, he has visions of his next case. He sees through the eyes of the dead, the last images imprinted on their retinas. His nightmares are riddled with clues he must decipher to hunt humanity’s Great White Shark—the serial killer. While he’s investigating the shocking slaughter of a seventeen-year-old girl at Big Bear Lake, the tormented soul of another dead child appears to him in broad daylight. Twelve-year-old Avery Reed reaches out to Ryker—a disheveled and haunted girl, unable to speak—held earthbound out of love for her grief-stricken brother, Sam. Avery’s presence draws Ryker into a sinister conspiracy and she has a desperate message for her brother, if she can make Ryker understand. Navy SEAL Sam ‘Mozart’ Reed has been haunted by the brutal death of his little sister Avery when he was only fifteen-years old. He vowed to seek and destroy the killer who splintered his family, wiping out everything he’d ever known. Nineteen years later, his darkest wish came true when he found Hurst, her alleged killer, and stopped him from murdering one last time. But when Mozart learns the FBI has reopened Avery’s case, he fears the worst. His SEAL team may have ended the carnage of a serial killer years ago, but for the first time, Mozart has doubts that Hurst had been the man who took Avery’s life. A heartless predator is still butchering young girls. Mozart’s worst nightmare is back with a cruel vengeance.
