Dawn - The Seventh Age, #1

For centuries, a global conspiracy of secret societies have hoarded magic, keeping it hidden from the rest of the world. Before the age of reason and science, magic ruled the world. Now, it's coming back. If most of humanity gets wiped out in the process . well, sometimes you have to break a few eggs. A group of anarchs and heretics in Chicago work to tear down the barrier that has kept humanity ignorant of demons, forgotten myths, and ancient legends.
Obsessed with discovering evidence of the afterlife, Mike Auburn's death-defying stunts have brought him closer than ever to lifting the veil of reality. However, his ventures to the edge have not gone unnoticed. The boss of a tenebrous organization recruits Mike to their cause. Nothing can possibly go wrong. Right? Before long, a world ruled by the scientific method and rational thinking is challenged by the supernatural.
Drawn out by the long-awaited return of magic, the dead, the damned, and the demonic will stop at nothing to bring it back for good. Suddenly, Mike is stuck at the center of a battle between the forces of reason, of good, of evil and everything in between. Dawn is a clash of American Gods, Constantine, and The Dresden Files.
