An FBI agent tracks a brilliant serial killer in New York—right back to her own cold-blooded past in a riveting thriller

FBI Special Agent Daniela “Dani” Vega was seventeen when her mother murdered her father. Ten years after Dani’s own damning eyewitness testimony sealed her mother’s fate, she’s starting to have doubts. What if she got it all wrong?

A veteran NYPD homicide detective agrees to reopen the closed case on one condition—Dani must help him find a serial killer who’s been operating throughout New York City for the past decade. If anyone can decipher his patterns, and his riddles, it’s a trained codebreaker like Dani. The killer knows this too. And his next riddle—and victim—are meant just for her.

For Dani, stopping a killer—and learning what really happened to her father—becomes more personal and more dangerous with each new twist. As secrets of the past are unearthed, the truth could forever change Dani’s life…and the lives of everyone she loves.

FOR NEARLY THIRTY YEARS A SERIAL KILLER HAS BEEN HIDING IN PLAIN SIGHT. SO HAS THE KEY TO AN FBI AGENT’S DARK PAST.

A family is murdered as they sleep. FBI Special Agent Nina Guerrera and her new team are tasked with determining whether there is any link between this attack and another triple homicide from four years earlier and more than two thousand miles away. In the process, they’ll discover a serial killer so cunning that his grisly trail of death spanning nearly three decades has gone undetected. Each crime scene reminds Nina of the ghostly Latin folktale of La Llorona, which terrified her when she was an abandoned and vulnerable child. Now it’s back to haunt her.

Nina has known evil, but these macabre reenactments are as disturbing as they are baffling. Now she must uncover the meaning behind the rituals as the evidence leads her in an unexpected direction—far closer to home than anyone could have imagined. As the team narrows in on a suspect, the present collides with Nina’s past in a twist of fate that forces her to make the ultimate sacrifice.
