Imagine a city within a city, where monsters walk the street and magic fills the night. This is New York, but not as you know it.

This New York is a city of magic and monsters. Where ordinary people live alongside demons and nightmares, completely unaware of them. New York is home to M, a man with a past... and a secret. He knows more about the creatures who call his city home than anyone else in the world. He walks between the two worlds, at home in neither but more than comfortable in both. M is the man the monsters call when things get bad.

And things are about to get really, really bad.
