Matthew Klein watched his son Logan hold a spirit board—just as Matt himself did thirty years ago—and speak in a voice that didn't belong to a ten-year-old boy. The demon Zurvan has found his new vessel, choosing the cruelest one possible: Matt's own child. For three decades, Zurvan has orchestrated this moment, first possessing the kind neighbor who ran toward the flames to help, then guiding Wilbur Ward's hands as he built the advent calendar from the charred remains of the original spirit board. Now the demon's patience has been rewarded. Matt's allies are few—Detective Davenport has finally seen too much to deny what's happening, and Father Olsen has confirmed they face an ancient entity whose methods are psychological torment followed by violence. But Anika believes her husband unfaithful, Matt's foster parents have arrived oblivious to the horror and bearing a spirit board as a gift, and the bodies continue to pile up: Steven's phantom crumbled to ash, Wilbur Ward's corpse rots in the crawlspace, Simon Welch lies dead from his own possessed fury. Four doors remain on the calendar. Four days until December 24th, when Zurvan's mid-winter celebration reaches its peak. The demon no longer hunts from the shadows—he wears Matt's son's face now.Get the print version of the novel: https://weirddarkness.com/AdventOfEvil#WeirdDarkness #ChristmasHorror #HolidayHorror #SupernaturalThriller #HauntedCalendar #DarkChristmas #HorrorStory #DemonicEvil #CreepyTales #YuletideTerror
