Over the centuries, the name 'Dark Angel' has become synonymous with all things evil, but is there any truth behind that legend?

The question becomes moot when another stranger appears, one more dangerous and terrifying than the first: Lucifer's brother, Michael. What can a mortal do when he finds himself caught between warring angels? Mark's choices are limited. The consequences? Apocalyptic.
