Possessions (Oni Press, 2015)

Gurgazon the Unclean has escaped the feeble confines of the Llewellyn-Vane House. Now she towers over the city, reigning destruction over all! And with the help of the Four Horsemen of the Apocalypse, there's no stopping her from bringing on the end of the world! Except, of course, for all the ghouls, ghosts, vapors, poltergeists, and ectoplasmic entities within the city limits. Do they stand a chance against Gurgazon the Pit Demon? Can the Apocalypse be stopped when it's only just begun? Find out in POSSESSIONS, BOOK 4: THE FINAL TANTRUM!
