The Harbingers series is a collaborative project involving four Christian fiction authors: Alton Gansky, Bill Myers, Frank Peretti, and Angela Hunt. Each cycle collects novellas from the different writers, all following a connected storyline about a team of individuals brought together by mysterious abilities and supernatural encounters.
The series launched in 2015 with The Call and produced entries rapidly, with most of the first twenty novellas published within two years. The stories range from haunted locations and demonic entities to science fiction elements and psychological suspense. The collaborative format gives each entry a distinct voice while maintaining the larger narrative thread.
