A doctor, a witch goddess, and the Four Horseman of the Apocalypse walk into a bar…Meet Erin Kelly. You can call her Doc.

Yes, she’s a doctor. A cardiothoracic surgeon from Boston, to be precise.

She’s also the cursed descendant of an ancient witch goddess who’s destined to stop the Four Horseman of the Apocalypse from monkey-stomping humanity into a primordial puddle.

How Doc’s supposed to do that exactly is a bit of mystery—especially to her.

No worries, though. She’ll figure it out. Right after she tracks down her aforementioned arcane ancestor. There’s just one small wrinkle—she’s not been seen in a thousand years. Maybe two.

Regardless, Doc and her impromptu coven of witches, prophets, angels, snarky hellhounds, and the occasional giant or two better hurry. The Horsemen are on the hunt. And the end times are nigh.

Good thing Purgatory’s nice this time of year, huh?
