From publisher blurb:
The world of Contagion is a dark and terrifying place. On the surface it is no different than the world you and I live in. Most people go on about their lives never realizing the terrors that walk among them.
Despite humanity’s vast ignorance, the horrors are there. Angels demons, gods and Hellspawn make war in the shadows. Clergy and Slayers rise from the human flock to protect their brethren and work God's will. Magi and Witches wield powerful magics in their pursuit of enlightenment.
There's a war in the shadows. Choose a side.
