Not only is magic real (and Maggie has it).
Not only are demons real (and Maggie has defeated one).
But fae are real (and Maggie needs to help them out).
Fae are real, and they are anchoring the door to their kingdom in San Francisco. Oh, and a dark creature that feeds on people's nightmares may have snuck out the door and be feeding on the lives of humans. Maggie can help out with that, right?
Once again, the worlds of tech and magic collide, and Maggie might be the only one who can save the world from the darkness.
