Jack Sparks died while writing this book. This is the account of his final days. In 2014, Jack Sparks; the controversial pop culture journalist; died under mysterious circumstances. To his fans, Jack was a fearless rebel; to his detractors he was a talentless hack. Either way, his death came as a shock to everyone. It was no secret that Jack had been researching the occult for his new book. He'd already triggered a furious Twitter storm by mocking an exorcism he witnessed in rural Italy. Then there was that video: thirty-six seconds of chilling footage that Jack repeatedly claimed was not of his making, yet was posted from his own YouTube account. Nobody knew what happened to Jack in the days that followed; until now.

Fourteen years later, the traumatic event haunts both Emilee and Gabriella, the homicide detective who handled the case. Together, they discover that similar home invasions have happened across America for decades. And when they launch a hunt for the 'key killer, ' they start to wonder if unnatural forces could be at work.
